I think there must be a UA/MP gremlin in the various computer systems. When I checked out of the Hilton Paddington last week, the FF number on my folio was that of a long-dormant UA/MP account I had. It was changed at the cashiers to QF [my HH default FF program], but when I checked my HHonors account online, the miles still appeared destined to UA. The really odd thing is that when I checked my profile, only three FF programs were listed: QF, AC and AA. There was no record of this UA/MP account number anywhere on my profile. It just popped up for this stay.
