What is Southwest Airlines check-in policy?
For years Southwest handed out A, B and C boarding positions in check-in order, so hitting "Check In" at exactly 24 hours mattered. That ended on January 27, 2026: Southwest now says it has "transitioned from open to assigned seating" and boards in "Groups 1 through 8" (southwest.com). Your boarding group is set by your fare, Rapid Rewards tier or Cardmember status, seat type and cabin location - not by your check-in time. Check-in still opens 24 hours before scheduled departure, and you still need it: it issues your boarding pass and, on a Basic fare, your seat assignment.
🔸 Here's what you need to know:
Check-in window: Opens 24 hours before flight; deadline 30 minutes before domestic and 60 minutes before international departures (75 for Aruba).
Priority Boarding: EarlyBird Check-In is no longer sold. To board earlier, buy Priority Boarding from 24 hours before departure until 30 minutes before; it is priced per flight, per Customer (southwest.com).
Boarding group: Groups 1-8, set by fare, tier or Cardmember status, seat type and cabin location - not by check-in time. Your seat is assigned, so checking in later does not cost you a seat.
Methods available: Online, mobile app, airport kiosk, curbside (at select airports), or ticket counter.
Bags: Southwest baggage check at self-service kiosks, ticket counter, or curbside (not via online check-in).
Cut-off times: Must be at the gate 10 minutes before departure, or your reservation may get canceled.
No-show policy: Cancel at least 10 minutes before departure to keep travel funds/points.
FondTip: Always use Southwest check flight status before leaving home, because showing up early is smart, but showing up for a delayed flight is unnecessary.
How does Southwest Airlines flight check-in work?
Southwest check-in (from 24 hours before departure) issues a boarding pass that, in Southwest's words, "will list your seat location and boarding group". Seats are assigned on every flight: Choice, Choice Preferred and Choice Extra fares pick a seat when booking, while a Basic fare gets a "Standard seat assigned at check-in or at the departure gate" (southwest.com). Boarding runs in Groups 1 through 8; overhead-bin space still follows boarding order, which is what Priority Boarding is for.
Steps for the Southwest Airlines check in process mentioned below:
Check-in timing: Southwest online check-in opens 24 hours before departure; the deadline is 30 minutes before domestic and 60 minutes before international departures.
Choose your method: Use Southwest.com, the mobile app, self-service kiosks, the ticket counter, or curbside (domestic only).
Enter details: Confirmation number + passenger name required.
Get boarding pass: Print, save to mobile, or retrieve at the airport.
Bags: Drop off at Express Bag Drop, ticket counter, or curbside (if available).
Arrive Early: Be in the gate area well before the 10-minute cutoff - Southwest may cancel the reservation of anyone not there 10 minutes before departure.
Boarding: By boarding group (1-8) printed on your pass; your seat is already assigned.
Upgrade Option: Buy Priority Boarding (available from 24 hours to 30 minutes before departure) to be among the first to board, or pick a Preferred or Extra Legroom seat when booking.

How to check in online for Southwest Airlines?
Remember the "refresh, refresh, refresh" panic at exactly 24 hours before your flight? With assigned seats, that race is over. Southwest check-in policy lets passengers check in online starting 24 hours before departure. By entering your confirmation number and name, you get a digital or printable boarding pass showing your seat and boarding group. Here's how you can do it:
1. Go to Southwest.com or open the Southwest® app.
2. Enter your confirmation number, first name, last name.
3. Click Check In to get your boarding pass (Basic fares receive their standard seat assignment here or at the gate).

When can I check in for a Southwest flight?
The early bird no longer gets the aisle seat on Southwest - seats are assigned, so timing matters for your boarding pass and deadlines, not for where you sit.
Southwest online check-in opens 24 hours before the original scheduled departure time. The deadline is 30 minutes before departure for domestic flights and 60 minutes for international (75 for Aruba), and everyone must be in the gate area with a boarding pass at least 10 minutes before departure or the reservation may be canceled (southwest.com). Your seat is fixed before you check in (or assigned at check-in on a Basic fare), so the time you check in no longer decides where you sit.
FondTip: Want the window without the scramble? Pick it when you book on a Choice fare. Want first dibs on overhead bins? Priority Boarding, sold from 24 hours before departure, puts you among the first to board.
What is Southwest Airlines baggage check-in policy?
Think of your bags as fellow travelers; they need their own check-in process too. Southwest's two-bags-included era is over for most fares: checked bag fees now apply on Basic, Choice and Choice Preferred fares - Southwest's Optional Travel Charges page lists $45 for the first bag and $55 for the second on U.S. mainland travel on or after April 9, 2026 - while Choice Extra fares and A-List Preferred Members still get two checked bags included, and A-List Members and Rapid Rewards Credit Cardmembers get the first bag included (southwest.com fee page). Each bag may weigh up to 50 lbs and measure up to 62 inches (L+W+H). After check-in you can check bags digitally from 24 hours before departure until 60 minutes before a domestic flight or 90 minutes before an international flight, then hand them over at the bag drop-off line, ticket counter, curbside, or self-service kiosk.
Wondering, "Do I really get a seat if I don't have a boarding pass?" The answer: nope, it's your golden ticket to board. Southwest check-in and boarding pass are tied together; you must check in (online, via app, or at the airport) to get your pass. Boarding passes can be digital (saved on your phone) or printed at kiosks/counters.
Check in from 24 hours before departure (EarlyBird Check-In is no longer offered).
Use Southwest.com or the Southwest® app or check in at the airport.
Enter confirmation number + passenger details.
Retrieve boarding pass → print, email to yourself, or save to mobile wallet.
Have it ready at the TSA checkpoint and boarding gate.
