Been trying to find availability on AB, but it is saying
Your request could not be processed at the moment.
[CAB:E0DA05]
No connections found for the entered data. You can find further information on the travel periods in the airberlin flight plan ».
However, from ITA I know there are flights. However, there it is TXL-AUH-MLE. AUH-MLE is on Etihad. Is this why it won't show up when trying to book an award on AirBerlin? I'm not even sure how to find any availability...should I be calling AA, using AA's booking online or call them since it is going to be AB and Etihad?
