We generally do not offer seat reservation at the time of booking. Instead, your seat is automatically assigned by the airline during check-in.
If you wish to choose your seat in advance, you can usually do so directly via the airline’s website. Use the booking number provided for each flight in your travel documents. Seat reservation through the airline is usually possible up to 24 hours before departure and may be subject to a fee.
However, with most airlines, choosing a seat during check-in is free of charge. Check-in typically opens 24 hours before departure. If you do not make an active choice, a seat will automatically be assigned to you during check-in.
