Air Berlin XL seats
 

Are they worth an additional €99?

How long is the flight? Are you tall or big?

From JFK to Düsseldorf. We are 5'8" and 6 foot tall

Sorry I should've mentioned that it's an international overnight flight!

We did it on our most recent flight from ATL to CDG and back on Delta. Cost $100 each leg. It was worth it to us. We are only 5'4" and 5"6" and we appreciated the extra room.

I flew VIE-DUS-JFK and back on Air Berlin and paid for the extra space. I am also 5'8" and loved having the extra room, especially on the overnight return.

Thank you all! Seat Geru is new to me....so thank you!

When you are looking at seatguru you should also look at the accompanying written "reviews" and note their row/seat number.

Seatguru can be inaccurate about details sometimes; you might also look for any youtube "reports" about flying on AirBerlin; sometimes those visuals can help you decide.
