Southwest Airlines: General Overview

Southwest Airlines is the largest low-cost carrier in the world and one of the most recognizable names in U.S. aviation. 

Unlike traditional legacy airlines, Southwest follows a point-to-point network, operates a single aircraft type, and emphasizes low fares paired with friendly, transparent service.

The airline is best known for its distinctive policies, including open seating, generous change and cancellation rules, and its popular Rapid Rewards loyalty program. 

With more than 4,000 daily departures and over 800 Boeing 737 aircraft in service, Southwest Airlines plays a central role in connecting cities across the United States, Mexico, Central America, the Caribbean, and the Bahamas.

Its customer-focused mission – “Low fares. Nothing to hide.” – has helped the airline consistently rank near the top of customer satisfaction surveys.

General Information

• Founded: 1967 (as Air Southwest, began flying in 1971)
• Headquarters: Dallas, Texas
• Tagline: Low fares. Nothing to hide.
• Alliance: N/A
• Frequent Flyer Program: Southwest Rapid Rewards
• Mission Statement: To connect people to what is important in their lives through friendly, reliable, and low-cost air travel.
• Daily Flights: Over 4,000
• Total Destinations: 117 (U.S., Puerto Rico, Mexico, Central America, and the Bahamas)
• Main Website: southwest.com

Major Domestic Hubs

Southwest Airlines does not operate a traditional hub-and-spoke network like legacy carriers. Instead, it runs a point-to-point system designed for more direct routes. 

Even so, several airports serve as key operational bases:

• Dallas Love Field (DAL): Corporate headquarters and central hub for operations.
• Chicago Midway (MDW): Major base in the Midwest with extensive U.S. coverage.
• Denver (DEN): Fast-growing operation with hundreds of daily departures.
• Las Vegas (LAS): A key leisure and connection base for the West Coast.
• Phoenix (PHX): Longstanding Southwest stronghold with extensive domestic service.
• Baltimore / Washington (BWI): Largest East Coast base, serving both business and leisure travelers.

Route Network

Southwest Airlines operates one of the largest domestic networks of any U.S. carrier. With more than 117 destinations across the United States, Puerto Rico, Mexico, Central America, and the Caribbean, it connects travelers to both major business centers and popular leisure destinations.

Unlike legacy carriers, Southwest Airlines does not belong to an airline alliance and does not rely on a hub-and-spoke model. Instead, it follows a point-to-point network, offering thousands of nonstop flights between cities that often bypass traditional hubs. 

This design reduces travel time and makes Southwest especially appealing for direct flights between mid-size markets.

Below are some of the key destinations where Southwest operates its most flights or sees the highest passenger traffic:

• United States: Dallas Love Field (DAL), Chicago Midway (MDW), Denver (DEN), Las Vegas (LAS), Phoenix (PHX), Baltimore / Washington (BWI), Houston (HOU), Los Angeles (LAX), Orlando (MCO), Nashville (BNA)
• Caribbean: Nassau (NAS), Montego Bay (MBJ), San Juan (SJU)
• México: Cancún (CUN), Mexico City (MEX), Los Cabos (SJD), Puerto Vallarta (PVR)
• Central America: Belize City (BZE), Liberia (LIR), San José (SJO)

While the international presence of Southwest is smaller than that of legacy carriers, its strength lies in domestic coverage. The airline frequently ranks as the largest U.S. airline by number of domestic passengers carried, thanks to its extensive nonstop routes and high flight frequency.

The combination of strong U.S. bases and expanding leisure destinations abroad makes Southwest Airlines one of the most convenient options for travelers who prioritize low fares, flexibility, and nonstop service between city pairs that larger carriers often overlook.

Fleet Overview

Southwest Airlines operates the largest fleet of Boeing 737 aircraft in the world. By sticking to a single aircraft type, the airline reduces training costs, simplifies maintenance, and ensures consistent passenger experiences.

• Boeing 737-700: Older model, seats ~143 passengers.
• Boeing 737-800: Larger model, seats ~175 passengers.
• Boeing 737 MAX 8: Newest addition, seats ~175 passengers, with updated interiors and improved fuel efficiency.

This all-737 fleet strategy has been a cornerstone of the Southwest Airlines identity. It provides uniformity for flight crews and reliability for passengers, while also enabling the airline to keep operational costs low.

Fare Classes And Seat Types Explained

Southwest Airlines keeps things simple by offering only one cabin class – Economy – but it divides its tickets into four fare types. Each option comes with its own rules, earning rates, and flexibility. 

Understanding the differences will help you book the right ticket for your trip.

Basic

Basic is the lowest Southwest Airlines fare and the most restrictive option. It is designed for travelers who need the cheapest possible ticket and are willing to sacrifice flexibility.

• Transferable flight credits (can be given to another Southwest Rapid Rewards member)
• Eligible for same-day confirmed changes and same-day standby
• Includes personal item and carry-on bag

TPA Pro Tip: This fare type is a sweet spot – offering more flexibility than Basic at only a small price increase on many routes.

• 14 Southwest Rapid Rewards points per $1 spent
• Priority boarding (Group A1 – A15)
• Free premium beverage (alcoholic drink)
• Free inflight Wi-Fi
• Two free checked bags included
• Includes EarlyBird Check-In automatically

Baggage Fees And Carry-On Rules

Southwest Airlines built its reputation on simple, customer-friendly policies. For years, “bags fly free” was part of the brand identity, but as of 2025, checked baggage is no longer complimentary for all travelers. 

While passengers still enjoy generous carry-on allowances, most will now need to pay for checked bags unless they hold elite status, book certain fares, or carry a co-branded credit card.

Carry-On Allowance

All passengers, regardless of fare type, are allowed both a personal item and a standard carry-on at no extra cost.

• Personal Item (free): Must fit under the seat in front of you. Examples include a purse, backpack, or laptop bag.
• Carry-On Bag (free): Maximum size: 10 x 16 x 24 inches. Must fit in the overhead bin.

Checked Baggage Allowance and Fees

Southwest Airlines now charges most travelers for checked baggage. Fees apply per passenger, per direction:

• First Checked Bag: $35
• Second Checked Bag: $45
• Third Bag and Beyond: $150 each

Exceptions (Free Checked Bags):

• Business Select Fares: Two free checked bags
• A-List Preferred Members: Two free checked bags
• A-List Members: One free checked bag
• Southwest Rapid Rewards Credit Cardholders: One free checked bag (for the cardholder and up to 8 companions on the same reservation)
• Active-Duty Military: Unlimited free checked bags (up to 20 per flight)

Overweight And Oversized Bags

Bags that exceed standard size or weight limits will incur extra charges.

• Weight Limit: 50 pounds per bag
• Overweight Bags (51 – 100 lbs): $100 – $200 per bag
• Oversized Bags (over 62 linear inches): $200 each
• Sporting Equipment: Special rules apply (golf bags, skis, bikes, etc. may have oversize fees waived).

Other Fees And Add-Ons

• EarlyBird Check-In: $15 – $99 per passenger, per flight
• Upgraded Boarding: $30 – $149 per passenger, per segment
• Unaccompanied Minor: $100 each way (ages 5 – 11, mainland U.S. routes)
• Pet Fee (carry-on): $125 within mainland U.S., $35 within Hawaii

How To Avoid Paying Southwest Airlines Baggage Fees

Even with the new policy, several strategies can keep costs down:

• Book Business Select fares for automatic free bags.
• Earn A-List or A-List Preferred status for extra baggage allowance.
• Use a Southwest Rapid Rewards credit card, which includes one free bag for you and up to 8 companions.
• If you are active-duty military, you receive unlimited free checked bags.

Southwest Boarding Process And Seating

Southwest Airlines is famous for its unconventional boarding process. 

Unlike most airlines that assign seats at booking, Southwest uses an open-seating model where passengers choose any available seat once they board. This system makes boarding quick, but it also means that your position in line can determine whether you sit in the aisle, the window, or somewhere in the middle.

Boarding Groups And Positions

When you check in, Southwest Airlines assigns you both a boarding group (A, B, or C) and a boarding position number (1 – 60). This determines when you get on the plane and how many seats will be left to choose from.

• Group A: First main group to board (following pre-boarding)
• Group B: Boards after Group A
• Group C: Final boarding group, usually with limited seat choice

TPA Pro Tip: The earlier your boarding position, the better your shot at an aisle or window seat, or prime spots like exit rows and bulkhead seating.

Check-In Rules

Check-in opens 24 hours before departure. Your position is based on how quickly you check in, so setting an alarm is essential.

• EarlyBird Check-In: For $15 – $99, Southwest will automatically check you in before the 24-hour mark, improving your boarding position.
• Upgraded Boarding: At the gate, you can pay $30 – $149 per segment to move into the coveted A1 – A15 positions (normally reserved for Business Select).
• Elite Benefits: A-List and A-List Preferred members receive automatic priority check-in, often securing earlier boarding.

Family And Companion Boarding

• Families with children age 6 or under may board after Group A but before Group B.
• Travelers with different boarding groups can board together, but only by waiting until the later position (the higher number must always defer to the lower one).

Seat Selection Tips

Since there are no assigned seats, a few strategies can improve your experience:

• Exit Rows and Bulkhead Seats: Offer more legroom, but fill up quickly.
• Front Rows: Quicker deplaning, great for tight connections.
• Middle Seats: Usually avoided, but may be your only option if you check in late.
• “Seat Saving”: Southwest discourages saving seats, but it still happens. Be prepared to politely ask if a seat is available.

Southwest Boarding Process In Action

At the gate, passengers line up in numerical order based on their boarding pass. Gate agents call groups in sequence (A, then B, then C), and travelers take their places at the numbered markers. 

Once your group is called, you scan your boarding pass and head onto the aircraft to choose any open seat.

This open-seating system may feel unusual for first-timers, but it becomes second nature after a flight or two. Many frequent Southwest Airlines passengers enjoy the flexibility – especially those who master check-in timing or invest in EarlyBird Check-In.

In-Flight Experience: Seats, Amenities, And Service

Southwest Airlines keeps its inflight product simple but enjoyable. While there are no premium cabins or luxury upgrades, passengers appreciate the roomy seats, free entertainment, and friendly service that make flying with Southwest feel approachable and reliable.

Seating And Comfort

Southwest offers a single-cabin layout across its fleet, but that does not mean comfort is overlooked. Seats are fairly generous compared to other low-cost carriers, and the uniform Boeing 737 fleet ensures a consistent experience.

• Aircraft Type: All Boeing 737s (737-700, 737-800, and 737 MAX 8)
• Seat Pitch: 31 – 33 inches (legroom comparable to or slightly better than most U.S. carriers)
• Seat Width: Up to 17.8 inches, among the widest in U.S. Economy Class
• Recline: Limited but comfortable for short and medium-haul flights
• Best Seats: Exit rows and bulkhead seats offer extra legroom but are first-come, first-served

TPA Pro Tip: Check in right at the 24-hour mark or buy EarlyBird Check-In if securing an aisle or exit row seat is a priority.

Food And Drinks

Food service on Southwest Airlines is straightforward but dependable. While you will not find elaborate meals, the complimentary snacks and affordable drink options are a nice touch for budget travelers.

• Complimentary: Coffee, tea, water, soft drinks, and light snacks (typically pretzels or crackers)
• Alcoholic Drinks: Beer ($6 – $7), wine ($6), liquor ($7)
• Holiday Specials: Complimentary alcohol is often offered on select holidays like New Year’s and July 4th

Wi-Fi And Entertainment

Southwest Airlines provides a strong lineup of entertainment options, though everything is accessed through personal devices rather than seatback screens. This keeps costs low but still gives passengers a variety of choices in the air.

• Wi-Fi: $8 per day, per device
• Live TV: Free through the Southwest Inflight Entertainment Portal
• Movies: Free streaming to your own phone, tablet, or laptop
• Messaging: Free with iMessage and WhatsApp

Atmosphere and Service

One of the most distinctive features of Southwest Airlines is its culture. 

Crews are known for their humor, friendliness, and casual style, often delivering announcements with personality and charm. This lighthearted approach adds to the relaxed atmosphere on board, making Southwest stand out from more traditional airlines.

Southwest Rapid Rewards Loyalty Program

Southwest Airlines rewards frequent flyers through its Rapid Rewards program. Simple, flexible, and popular among U.S. travelers, Rapid Rewards is one of the most valuable loyalty programs for domestic flying. 

Points are tied directly to the price of a ticket, which makes redemptions predictable and easy to use.

How to Earn Southwest Rapid Rewards Points

Members can earn points in several ways:

• Flying: Points are based on the fare type purchased.
  • Basic: 2 points per $1
  • Wanna Get Away Plus: 6 points per $1

  • Business Select: 14 points per $1
• Credit Cards: Co-branded Southwest Airlines Rapid Rewards® Credit Cards (personal and business) offer welcome bonuses and everyday earning.

• Hotels, Car Rentals, and Partners: Earn with hotel stays, car rentals, and partners like Rocketmiles, Marriott Bonvoy, World of Hyatt, and more.

TPA Pro Tip: While Chase Ultimate Rewards and Bilt Rewards transfers do not count toward earning Companion Pass, they are still one of the best ways to quickly book Southwest flights with points.

How To Redeem Southwest Rapid Rewards Points

Rapid Reward points can be used for much more than just flights. Redemption options include:

• Award Flights: Points are tied to the cash price of tickets, averaging 1.3 cents per point.
• No Blackout Dates: If a seat is available for purchase, you can book it with points.
• Other Redemptions: Points can also be used for hotels, gift cards, and experiences – but flights provide the best value.

The Southwest Companion Pass is widely regarded as one of the most powerful perks in all of travel rewards.

• What It Is: Choose one person to fly with you for nearly free (just taxes and fees) every time you purchase a ticket or redeem points.
• How to Earn:
  • Fly 100 one-way flights in a year, or
  • Earn 135,000 qualifying Rapid Rewards points in a calendar year
• Validity: Companion Pass is good for the rest of the year it is earned plus the entire following calendar year.
• Best Strategy: Time your credit card sign-up bonuses and points earning for January, which can unlock almost two full years of free companion travel.

TPA Pro Tip: If you fly Southwest Airlines even a handful of times each year with a spouse, partner, or family member, earning the Southwest Companion Pass can literally cut your flight costs in half.

Pro Tips For Flying Southwest

Southwest Airlines is simple compared to many airlines, but there are still plenty of strategies that can make your flights smoother and cheaper. 

These tips will help you save money, find better seats, and maximize the value of your Rapid Rewards points.

Check In Early

Your boarding position is everything on Southwest Airlines, since seats are not assigned. The earlier you check in, the better your chance of snagging an aisle, window, or exit row seat.

• Set An Alarm for exactly 24 hours before departure.
• Consider EarlyBird Check-In ($15 – $99) if you do not want to worry about timing.
• Upgraded Boarding ($30 – $149) can move you into the A1 – A15 group for guaranteed early access.

Choose Fares Strategically

Not all fare types are created equal. While Basic is cheapest, it often comes with restrictions that can cost you more later.

• Wanna Get Away Plus often provides the best balance of price and flexibility.
• Anytime fares can be refunded, giving peace of mind for business travelers.
• Business Select earns the most points and provides priority boarding.

Maximize Rapid Rewards

Earning and redeeming points wisely can unlock big savings, especially with the Companion Pass.

• Use Chase Sapphire Preferred® Card, Chase Sapphire Reserve®, or Bilt Mastercard to transfer points 1:1 into Southwest Rapid Rewards.
• Stack points by shopping through the Southwest Shopping portal and using the Southwest Dining Rewards program.
• Time Companion Pass earnings for January to enjoy nearly two full years of free companion flights.

Pick The Best Seats

Since there are no assigned seats, small strategies can make a big difference in comfort.

• Exit rows and bulkhead seats offer extra legroom.
• Front rows allow for faster boarding and deplaning.
• Avoid middle seats by checking in early.
• Be prepared for “seat saving” – it happens, but most passengers are accommodating if you ask politely.

Travel Smart During Busy Times

Southwest Airlines flights fill up fast around holidays and peak travel seasons. Planning ahead will save you stress.

• Book Early. Southwest fares rise closer to departure.
• Morning Flights are less likely to face delays.
• TSA PreCheck or CLEAR can cut down on long security lines.
• Keep a backup flight in mind, since the Southwest Airlines No-Change-Fee Policy makes it easy to adjust plans.

Customer Satisfaction, Reviews, And Safety

Southwest Airlines has long been known for its customer-first approach, with consistently high rankings for service and satisfaction. 

While it does face challenges with delays and baggage handling, the overall passenger experience remains one of the strongest among U.S. airlines.

Customer Satisfaction

Southwest has been a favorite in customer surveys for decades. Its straightforward pricing, friendly crews, and flexible policies make it especially popular with families and leisure travelers.

• Ranked #1 in the DOT Consumer Satisfaction Index for 22 of the last 26 years
• Strong reputation for reliability, affordability, and transparent pricing
• Consistently high scores in J.D. Power’s airline satisfaction studies

Performance And Reliability

Southwest does well in satisfaction rankings but faces challenges with operational performance, particularly on-time arrivals.

• On-time Performance (2024): 78.9% (ranked 4th among major U.S. carriers)
• Mishandled Baggage: Ranked mid-pack, 5th out of 10 in 2024
• Involuntary Denied Boardings: 0.08 passengers per 10,000 – higher than some competitors

Common Complaints

Like all airlines, Southwest Airlines receives complaints, though fewer than many of its peers. Most negative feedback relates to delays and baggage issues rather than service.

• Flight cancellations and delays
• Misconnections from late-arriving aircraft
• Occasional frustration with open seating and “seat saving”

Final Thoughts

Southwest Airlines continues to stand out as one of the most unique and customer-friendly carriers in the United States. Its mix of low fares, transparent pricing, and flexible policies makes it a favorite among leisure travelers and frequent flyers alike. 

While the airline is evolving – with new baggage fees, updated fare types, and assigned seating planned for 2026 – it remains one of the most accessible ways to fly.

From understanding fare options and boarding groups to maximizing Rapid Rewards and the coveted Companion Pass, travelers who know how Southwest operates can unlock exceptional value. 

Even with a few quirks and operational challenges, the combination of affordability, service, and loyalty perks makes Southwest an airline that delivers far more than its low-cost label suggests.

If you are planning a vacation, a family trip, or regular business travel, Southwest can help you get there with less stress and more savings. 

By checking in early, booking fares strategically, and using points wisely, you can stretch your travel budget further than ever.

With a little preparation, Southwest Airlines can take you further for less – turning your travel dreams into more affordable, more enjoyable memories.
