Southwest Seat Maps & Selection

With Southwest, you’ll not see seat assignments automatically. Instead, passengers choose them during boarding. You can see the seat map and check in early if you want better seat options. Priority boarding? Simply add EarlyBird or opt for Business Select for a head start.

  • BusinessSelect: This is Southwest’s premium fare with guaranteed A1-A15 boarding. You get free drinks with this fare, plus maximum Rapid Rewards points. If your plans change, this fare is fully refundable.
  • Anytime: This fare is also flexible, refundable with more Rapid Rewards points, and offers early boarding options. It’s perfect if you wish to change without premium pricing.
  • WannaGetAwayplus: If you book this fare with Southwest, it’ll offer you lower fares with added flexibility like same-day confirmed changes and transferable flight credits. 
  • Wanna Get Away (Basic): Lastly, there’s the most affordable fare, which offers you standard benefits like two free checked bags. This is a non-refundable fare, but you can reuse funds for future travel within a year.

Southwest Upgrades

Upgrade to Business Select for perks like A1-A15 boarding position, early seat access, overhead bins, free drink, and bonus points - on eligible flight segments. You can upgrade if your flight segments are within 24 hours of departure. But if you’re looking to book cheap business class flights, Dreamtriphub offers great alternatives with other airlines.

Southwest Check-in & Onboard

Checking in with Southwest is as smooth as ever, due to their in-flight experience where passengers are treated with light snacks, comfortable seats, and more legroom than you’d expect from a low-cost airline. As for check-in, there are four ways to do that.

Online & Mobile Check-in

You can check in around 24 hours before your flight is scheduled via Southwest’s official app or website. If you’ve got EarlyBird Check-In, you’ll be automatically checked in, elevating your boarding position.

Airport Check-in

Prefer to do things in person? Go to the airport and use self-service kiosks. If not, speak with a Southwest Airlines agent to get your boarding pass.

Baggage Check-in

Next, you need to drop your bags off at the designated counter. The airline allows passengers to carry two free checked bags per person, and this is one of the main reasons why travelers choose Southwest so often.

Boarding Times

Southwest Airlines has a unique boarding system with groups A, B, and C. Your position is dependent on at what time you check in. So, the earlier you board, the better. 

In-flight Services & Entertainment

As far as in-flight services are concerned, you get complimentary soft drinks and snacks, along with free TV, movies, and messaging on your device. This makes your flight experience even better.

Wi-Fi & Comfort Options

You get affordable Wi-Fi on the flight, plus roomy seats with extra leg space. Yes, we know it’s not first-class, still the comfort is impressive for an economy airline.
