UA said what? UA told C5 to come up with a plan immediately after United reduced their flying, or United would pull the contract? I seriously doubt that.UA came to C5 and said "If you don't get us some workable plan in short order, you're all done." At least that's what someone said who was in the room. I'm fairly certain C5 doesn't have to pockets to do that or they would, this is actually a decent place with some shotty problems before all this happened.
And this is only for April. May will be decided in a few weeks. It could get worse and I believe it will. These agreements only staunch the bloodletting for now.
If C5 wants to run fat on pilots, that’s C5’s issue, not United’s.
