I can say with absolute certainty that there is no way every single UA activity/glitch/cock-up will be rectified perfectly so that the world is as it would have been if this integration had actually been completed successfully. It is going to take weeks for them to work through idiosyncratic scenarios and at a point some of us just won't pursue the appropriate outcome any farther. I'm writing off my 2 global upgrades and 6 regional upgrades that have been double deducted. There is no way in hell I'm booking a work-related TPAC or TATL for April/May on this airline anyhow when they can't even correctly credit my flight from last Wednesday or keep me in my assigned seat for more than six hours. Those are paid C, as are my TCON flights. I'll be at the front of the bus regardless of status on any airline. UA had that business from me because, frankly, I liked them more than anyone else.

These types of mergers of equals have large friction costs within both customer bases. You can count at least my next two months of business as a fraction of those costs from the UA side. Given how well DL has been taking care of me as a Plat it's likely to be much more time than that as this will tip the scales as to which airline I put more BIS in on this year. I may fall to 75K on UA for the first time since I graduated college.

This is why companies that aren't desperate don't enter into these transactions.

Not a single balance within my MP account is correct. Not a single existing itinerary is lacking at least one issue. My patience is not limitness, nor should it be.
