thanks,
kipper--i figured it out...i was at the wyndham o'hare in may during a mileage run--got a vdb and united put me up for the night before sending me on to nrt the following day (in f

).
no wonder i didn't remember--i didn't get a stay credit since it was a negotiated rate with united, and i don't have a credit card folio 'cause there were no charges to me. frankly, i'm trying to figure out which of my three ccs i used...as long as it wasn't my (main) amex, i'm tempted to get a new cc number.
still think it's weird i've seen nothing about this anywhere else...maybe it was a very small breach.
