Air Berlin experiences?

Has anyone used ZEDs on AB? I may use them this weekend for STR-NAP, and I'd appreciate any insight about their operation, customer service, and ZED policies.

Thanks

I took them for one flight, SVQ-PMI. No problems at all, and my airline had an ezed agreement with them. I believe this was only my second time flying ZED (first being MAD-SVQ a few days earlier on IB) and it was fine. Since we don't really have much for AB people around here, I called their reservations line. They didn't give specific numbers, but they were at least willing to tell me if a flight was worth trying for or not.

I've used them once, DUS-MUC.
Had eZed, and everything was flawless. As usual with foreign ZEDs, I was assigned a seat at checkin, not at the gate. Arrived from ATL, and stuck in customs for over an hour, causing me to miss my original connection. Agent at counter just listed me on another flight without making me jump through hoops. Service on board was just fine.
