Personally I'm much more concerned about having financially stable airlines in the USA than the perks. If I buy a coach fare (which is all of my travel), I expect to ride in coach.

Now then, if United were to eliminate Economy Plus for Premiers, I would seriously consider alternative airlines. But I'd stay loyal with almost any other reduction in perks save that.

I felt a little guilty sitting on a IAD-SEA flight a couple weeks ago, upgraded to F using 500-milers on my $248 round trip fare, next to a guy on his way back from FRA probably on a C fare (or at least H so he could upgrade). The gravy train has to end soon.
