| This was my first time flying with Air Berlin on a trip from Chicago to Salzburg and a return flight from Prague to Chicago. It was the worst airline experience I have had in about 20 years of frequent flying. Here are some key reasons: Customer Service is non-existent. No one ever answers their phone number and their online service always returns an error message. I tried for two weeks both online and on telephone with one simple request, to upgrade my seat on my return flight (in other words, pay them more money!). One night, with Expedia on the line with me, we waited on hold for 95 minutes and I finally fell asleep at 1am. Also, with one exception on return flight, every single Air Berlin person I dealt with was not only extremely poor at customer service, but even rude. One flight attendant was just mean to the person in front of me who asked if they could give them their trash. Another flight attendant was rude when I asked a simple question at the counter. Another in baggage claim area in Berlin was rude. Their seats in economy are smaller than any other airline seat I have experienced. I had an eight hour flight with the seat back in front of me literally 10 inches from my face. I am 5 feet 5 inches and my knees hit the seat in front of me the whole time. Be aware they will charge you $60-100 extra just to pick a seat - any seat, including economy - in advance of your flight. The WIFI does not work. I paid for WiFi going over and back and was never able to get on it. The flight attendants were no help whatsoever and were again rude when I inquired The worst part was that I experienced two delayed flights - one from Berlin to Salzburg and one from Berlin to Chicago. Both were handled terribly. When I arrived late in Chicago to make my connection to MSP, I literally ran to the gate and got there in time to get on the flight, but Air Berlin without my consent or knowledge had changed my flight to a flight 4 hours later instead and American Airlines would not let me get on my original flight. When I called Air Berlin to complain about this while sitting in ORD for 4 hours, I again waited on hold for 2 hours and finally decided they did not deserve any more of my time or effort in giving them feedback. They probably won't even read this or care, but I wanted to alert other travelers - avoid this airline!
