OK, I just have to give "the other side" by saying how things have worked correctly for me so far.

I flew on 3/2 and everything posted correctly within a couple of days, including the 100% RDM bonus still in effect on that day.

I flew on 3/16 on a Z fare. The miles posted a few days later. I think I received too many RDMs. I was given a 50% RDM bonus for the Z fare and a 75% RDM bonus for being Premier Platinum. I was also given a 50% PQM bonus. Whatever. I'll take it.

I booked an international flight for May last weekend, with mileage/co-pay upgrades both ways. I selected a 7-day hold for $21. The held reservation shows on my reservations listing and my credit card was charged $21. I have seat assignments in the proper upper classes the whole way.

Now when I go to pay for the held reservation tomorrow who knows what will happen? But I've got some time until I fly to get them to fix it if something goes wrong.

Oh yes, all my United/Continental miles merged correctly as well (though most were United miles).

I write this just to reflect at least one positive experience on this board.
