I called in today to activate my card making a statement to the CSR that I noticed they are not putting the MP number on the new Explorer card like the old UA MP Visa. He said, that was purposefully done to help protect card users should they lose their card. My guess is this was done in preparation for the merged accounts knowing they'd have to convert everyone with a MP number to a OP number. Not having the old MP number on the card makes it much simpler to complete the task - one less thing to worry about since they don't have to reissue the card.

Also, as a data point, when activating my card the CSR confirmed my 50k bonus AND the 2 club passes that I should receive in 8-10 weeks. In addition, I will receive another 2 passes each year I renew the card. FWIW, my T&C's that came with the card made no mention of the initial club passes stating only that I'd receive them AFTER my first year anniversary.

Peace!
