This morning, I decided to mix things up and change a previously booked business class award, so it now goes FRA-BCN-DOH-SEZ-ADD-IST-CPH. That involves three different Star Alliance carriers (LH, ET and TK) and Qatar Airways. Immediately after booking online, I received a confirmation email. However, now I cannot view the reservation online, and it is showing as FRA-ZRH (the first leg of my old ticket)... 1) How long should I wait before calling them? 2) Has anybody been to ADD? Is 4 hours enough connection time?
