Check-in, seats, and baggage

After your flight is confirmed, you manage check-in and extras directly with the airline using your booking reference (PNR).

Checking in

Check-in usually opens 24 to 48 hours before departure. Go to the airline's website or app, enter your booking reference, and follow their check-in process. You can also select seats there.

Baggage

Baggage rules are set by the airline and vary by fare class and route. Find the baggage policy for your booking on the airline's website using your reference. You can also add checked baggage through Duffel support before your flight.

Your booking reference is in your confirmation email and your Cryptorefills order history. See what to do with your booking reference.
