How Southwest Connections Are Made

Go to the boarding gate at the point of origin, go through security check, board the first flight, walk to the next boarding gate, and board the second flight. For international flights, passengers must go through immigration and customs clearance, as well as bag re-checking.

Check-In at Southwest Airlines

It can be done online, through the Southwest mobile app, airport check-in kiosks, Skycap if available, and the ticket counter personnel. In general, online check-in starts 24 hours before departure time.

The standard cutoff policies usually demand that for domestic travel, check-in has to be made 30 minutes before departure, and for international travel, it needs to be made 60 minutes before departure; there are some exceptions for certain airports.

How Early Should You Be at the Airport for a Southwest Flight?

Take into account time needed for parking/transit, security, baggage check-in, size of the airport, kids, assistance, and holiday crowds. Travel to international destinations always takes more time. You should follow current guidelines of Southwest concerning airport arrival times rather than a general arrival time guideline.

Southwest Airlines Boarding Policy

Starting from January 27, 2026, for flights departing from that date onwards, Southwest employs assigned seating and boarding numbers rather than its previous open seating with boarding A/B/C groups. The boarding group depends on the fare type, seat type, Rapid Rewards membership, and card benefits.

Basic fares usually get standard seat assignment and board last. Eligible travelers can be offered preboarding or priority boarding. Check your app and airport displays for updates.

  • Basic: Least flexible terms; standard seat selection at the time of check-in with stringent change policies.
  • Choice: Standard seat selection whenever available.
  • Choice Preferred: Preferred or standard seat selection whenever available.
  • Choice Extra: Extra legroom seat whenever available with more flexible terms.
  • There is no dedicated First or Business class on southwest 737 aircraft.
