Sent a PM to Shannon already - I lost my plum seat assignments for the intl legs of PMUA flights starting 3/13. Domestic legs are fine. My previous seat assignments for the intl legs are showing as taken, and the only remaining seats are the center business seats (renovated 777). I'm really really hoping that those previous seats are still mine, and the reservation just isn't linked correctly, but postings here from other people who have called into UA aren't encouraging.

Are there any people who *haven't* lost intl seat assignments for PMUA travel? Is there any pattern to this? My fares were class D for the intl legs, class A for the domestic legs, flying out 3/13 and returning 3/18. Thanks!
