I just booked a flight on EVA for July, knowing they will be in the * Alliance by then. During the web booking, United was presented as an FFP option. I know they aren't in the alliance yet, so maybe this is from some codeshare deal?
But the weird part is that the Eva website doesn't accept the new United CO numbers. I had to put my old UA MP number in to get the flight booked. I hope they straighten that out in the next few weeks! I'll bring my card to the airport in any case.
Another weird thing is that I was able to give myself a seat assignment on the A330 outbound, but not on the return flight which is an MD-90.
