This depends on the type of airline you are flying with. There are two options:
1. Low-cost airlines (such as Ryanair, easyJet, Transavia, WizzAir)
With low-cost airlines, you can find your reservation number or booking code on the booking confirmation we send you via email, immediately after you have booked a flight. You can also find your booking confirmation on MyGate1.
At low-cost airlines, you do not need a ticket number. You can find more information about checking in at low-cost airlines here.
2. Other airlines
You can find your booking reference and/or ticket numbers on the tickets we send you via email no later than 18 days after booking. We will always send you your tickets no later than 24 hours before departure.
Attention: Your ticket number(s) and/or booking reference do not come with the booking confirmation we send to you via email immediately after booking.
