Online check-in Air Berlin
Air Berlin, as of my knowledge cutoff in September 2021, was a German airline that ceased operations in 2017. The airline filed for insolvency and subsequently ended its flights.
As a result, there is no available online check-in for Air Berlin flights since the airline no longer operates. If you have any further questions or if you are looking for information about other airlines, please let me know, and I'll be happy to assist you.
