Online check-in opens exactly 24 hours before your scheduled departure time and closes 30 minutes before departure for domestic flights or 60 minutes for international flights. There are no fees for check-in via any method.

Steps to check in online:

  1. Visit Southwest.com or open the Southwest mobile app 24 hours before departure.
  2. Enter your confirmation number and last name.
  3. Select your boarding position (based on your check-in time).
  4. Receive your boarding pass digitally or print it at home or airport kiosks.

Practical tip: Set a reminder for exactly 24 hours before departure to secure an earlier boarding position, especially for popular routes or peak travel times.

What if I miss online check-in?
You can still check in at airport kiosks or the ticket counter, though you may receive a later boarding position. However, check-in at the counter closes 30 minutes before domestic departures and 60 minutes before international departures.
Can I check in at the airport without using online check-in?
Yes. You can use self-service kiosks or the ticket counter for check-in on the day of travel, but online check-in 24 hours in advance typically gives you a better boarding position at no additional cost.
