The Guide to Southwest Priority Boarding

Southwest Airlines once had an unconventional approach to its boarding procedures by not assigning seats — at least for now. Instead of seat numbers, the airline assigns every passenger a boarding position number that determines their boarding order. The earlier you board, the more options you have for where to sit. 

However, starting Jan. 27, 2026, that will change, as the airline transitions to a more traditional group-based boarding system and assigned seating.

When you check in for a Southwest flight, you’re assigned a boarding group (A, B or C) and a boarding position (from 1 to 60-plus). This is the alphanumerical order in which you’ll board an aircraft.

The earlier you check in, the better boarding position you’ll get, and the higher chance you’ll have to store a bag in the overhead bin. Typically, window and aisle seats get taken first, which is why having an early boarding position is conducive to avoiding the dreaded middle seat.

At the gate, you’ll find numbered posts designed to organize the boarding queue. When the boarding process starts and your group is called up, you will simply line up in order according to your boarding pass and wait for your turn.

When you get onboard, select an open seat and stow your belongings in the overhead compartment above it.

Once group-based boarding takes effect, passengers will be assigned a group based on a variety of factors, including their ticketed fare and whether they hold elite status or a Southwest credit card.

Here's a quick rundown of how boarding groups will generally work:

• Groups 1-2: Choice Extra fares, A-List Preferred members, A-List members who upgrade to an Extra Legroom seat and any passengers who purchase an upgrade to Extra Legroom.

• Groups 3-5: Choice Preferred fares, A-List Members in a Preferred or Standard seat, and Southwest credit card holders (cardmembers board with Group 5).

• Groups 6-8: Choice fares and Basic fares, with Basic being the last to board.

Southwest priority boarding allows you to snag a more favorable boarding position. There are currently two ways you can onboard a Southwest plane earlier than others: EarlyBird Check-In and Upgraded Boarding.

• EarlyBird Check-In automatically reserves a boarding position for you 36 hours before departure, so you don’t have to be stressed about getting a good boarding position. Note that you still have to check in for your flight within 24 hours of departure, and you still might end up in groups B or C if many passengers on your flight also purchased EarlyBird Check-In.

• Upgraded Boarding. For a fee, passengers can purchase Upgraded Boarding. Upgraded Boarding guarantees an A1 through A15 boarding position on a Southwest flight (if available).

Once assigned seating takes place, customers will be able to purchase Priority Boarding 24 hours prior to departure, putting them in the first group to board.

Southwest credit cards with boarding benefits

Southwest cards don't automatically get you priority boarding under the open seating system, although that will change with assigned seating. However, they do offer reimbursements if you purchase upgraded boardings through the end of 2025.

Purchase EarlyBird Check-In

One of the ways to get an earlier boarding position when flying Southwest is to pay for EarlyBird Check-In for your upcoming flight. This option comes in handy when your flight is early in the morning and you’d rather stay asleep the day before or you know you’ll be in a meeting and won’t be able to check in at the 24-hour mark yourself.

Note that EarlyBird Check-In doesn’t guarantee that boarding group A would show up on your boarding pass, but it increases your chances at a higher group.

The cost of EarlyBird Check-In starts at $15 and goes up depending on your flight. It applies only to one-way flights, and you’ll have the option to pay for EarlyBird Check-In per each one-way trip individually if you have a round-trip itinerary. 

Purchase Upgraded Boarding 

You can purchase a Southwest Upgraded Boarding — and guarantee an A1 through A15 boarding position — starting 24 hours before departure. The cost is variable and starts at $30 per flight segment, reaching as high as $80 per segment.

Book the right fare class

If you purchase a Southwest Choice Preferred (previously Anytime) fare, an EarlyBird Check-In is included. You’ll be assigned a boarding position 36 hours prior to departure.

Passengers who book or upgrade their Southwest ticket to a Choice Extra (previously Business Select) fare are guaranteed an Upgraded Boarding position in the A1 through A15 group.

Carry select Southwest Rapid Rewards credit cards 

One option to get complimentary EarlyBird Check-In is by holding select co-branded Rapid Rewards credit cards. For example, the Southwest Rapid Rewards® Plus Credit Card and the Southwest Rapid Rewards® Premier Credit Card members receive two EarlyBird Check-Ins per year.

Meanwhile, the Southwest Rapid Rewards® Priority Credit Card and the Southwest® Rapid Rewards® Performance Business Credit Card do one better: Cardholders receive four Upgraded Boardings per year (based on availability), so you can improve your boarding position that way.

Reach elite status with Southwest

A-List and A-List Preferred members receive priority boarding for everyone booked on the same reservation as boarding positions get assigned to elite Rapid Rewards members 36 hours before departure — so you don’t have to purchase EarlyBird Check-In separately.

Travel as a family

If you’re traveling as a family, then you’re eligible for Southwest priority boarding. One or two adults traveling with a child 6 years or younger can board after the A group is boarded, but before the B group is called. This applies only if both parents are assigned boarding positions in groups B or C. 

If you have an A group boarding position, you don’t need to wait for family boarding.

Use your military benefits

Similar to families, U.S. military members who carry a valid military ID can board between the A and B groups as well.

The Southwest boarding process isn’t for the faint of heart, but if you know what to do, you can position yourself in a higher boarding group than your fellow passengers.

Although Southwest priority boarding isn’t based on the cabin class you fly, you can get the perk by:

• Purchasing EarlyBird Check-In or Upgraded Boarding.

• Carrying a credit card that offers priority boarding benefits.

• Purchasing a higher fare ticket.

• Being an elite member.

• Using perks extended to families and military members.

If none of these apply to you and you don’t want to pay for an improved boarding position, make sure to check in at the 24-hour mark to give yourself the best possible chance to avoid boarding a Southwest plane last.

However, keep in mind that everything will change for flights starting Jan. 27, 2026, as Southwest moves to an assigned seating model with boarding groups.
