| San Francisco to Munich. I started flying with Air Berlin from Germany to the US for business during a period of strikes by Lufthansa. I did a few flights with them with a few minor problems (delayed flights, delayed luggage); I kept using them as I had already a bunch of miles and a gold status, but the last one was very bad and is the last drop. Connecting in Berlin will require you to change terminals by walking outside and going over security again. Their lounges are so bad that are almost always worse than the comparable regular waiting areas from better airlines. A lot of their web site is not working, specially if you are accesing it from outside of Germany. Their phone app is buggy and of very limited functionality. It is very hard to get hold of them on the phone, you have to navigate a maze of menus to get there and then wait for long periods of time. Their phone service is very fragmented, once I get to talk with someone it often happens that he or she can not do what I need and I need to call again. My average has been four calls to get anything done; this is in total with waiting and menu navigation about 45 minutes. Their phone service is not 24 hours, if you are in a different time zone than Germany you may have to actually wake up in the middle of the night to call. It is practically impossible to make use of miles for flight upgrades in their own flights. It is effectively impossible to use their miles to upgrade or buy any service from other airlines on the network. Booking an award fligh on their own flights requires you to call them, again, this is difficult; you cannot do it online. My last return flight was cancelled and I arrived with a 12 hour delay back home, losing a whole work day; they didn't offer lounge access during my 12 hour wait at the San Francisco airport. Now they are delaying and dragging their feet with lots of bureaucracy to pay the compensation mandated by EU regulations. This is just what I can remember in one go, the list can go on. I definitely do not recommend using Air Berlin.
