When booking a flight via Atlatos, you can make a seat reservation in the last step before the final booking.
Depending on the release of the company, only free or paid seats can be booked.
If a booking of paids seats is desired and currently not possible, this can be released via the travel policy. The release can also be made only for a special group of people.
Please note that the airline is free to change the seat selection in the aircraft for internal reasons. The seat request is therefore not 100% guaranteed.
