If you have booked a seat, it will be shown to you during Web Check-in. You can exchange this seat for another free seat at any time. You will not be charged if you change to a seat in the same category, but you may be charged for changing your seat to a different category (e.g. XL seat), depending on the fare you have booked.
Our system will automatically assign you a seat if you have not made an advance seat booking. You may change this automatic assignment and select another free seat at any time. You may be charged for changing your assigned seat, depending on the fare you have booked. You can find more information on the terms and conditions of your fare in our fare overview ». When possible, our system will assign adjacent seats to passengers travelling together. However, this is only possible if adjacent seats are still free when you check in. We recommend you check in as early as possible. You can use our online Web Check-in at airberlin.com or check in with the airberlin app, from 30 hours before departure.
