I booked MLE-AUH in J for 2 in October on one award, and then another award the next day AUH-JFK-RDU in F/Y.

I may even add an extra night in AUH.
For some odd reason when I look on ExpertFlyer F cabin is showing empty, but when I go to manage my booking on EtihadAirways.com it shows the cabin full and I cannot select seats. I guess I will have to call Etihad to select
