Soooo...Ethiopian airlines will not be flying non-stops from LAX to Dublin after December. Luckily I caught wind of this. Yesterday I contacted United Air (we had used UA f.f. miles) and they knew nothing about this. I persuaded them to look at the Ethiopian website as if they were trying to book our flight and see for themselves "This flight does not exist". They did and immediately put us on a United flight (still Biz Class). Unfortunately not a non-stop but a reasonable connection in ORD.

F.F. seats were not showing available but they opened 2 seats for us. Be persistent !
