I thought about calling United to see when my mileage from three flights I took after 3/3 would post, but decided to wait and see what happened. Judging from all the people on this channel that were calling constantly, I'm glad I didn't bother because the lines were jammed
Anyway, all the mileage showed up yesterday or today ... and in fact, it looks like one of my flights posted more than is normal. Will check it out later to figure out why. Probably because it's a different fare class than normal.
BTW, finally flew the new lie-flat seats. They'd kept a plane with the old 156 deg seats on my main int'l routes and just introduced a 767-400 with the new seats. I gotta say, I like them a lot. I think United is now my favorite long-haul carrier.
