SWISS online check-in and seat changes
SWISS offers boarding passes by email, for printing, and through app or Wallet storage. The seat you receive and the price of changing it depend on the fare and seat category. When no seat was reserved, SWISS assigns one at check-in; selecting a different seat may cost extra. Under the stated conditions, a previously booked seat can be changed at check-in to the same or a lower category without an additional check-in seat-change fee. Review the seat and boarding pass after completing the process. With checked baggage, you still need airport bag drop. Keep the online opening time separate from the airport’s reporting, baggage-acceptance, and boarding instructions; this page does not supply a single deadline for every SWISS departure.

Important unknowns
- Route-specific airport deadlines and available seat inventory remain unknown.
