Hello. Sorry if I posted in the wrong thread, but I think my question applies more towards this program. I was just approved for the first card I am going to churn, the US Airways Premier World Mastercard. Question on 2 of the benefits please. When I travel for work, I have to use my American Express Corporate card for all charges. The US Airways Premier World Mastercard comes with 2 unique benefits that I am not sure I can take advantage of: First class check-in and Zone 2 boarding on all US Airways flights One complimentary US Airways Club® day pass every year To take advantage of these features, do I need to actually book my ticket with this card? I couldnt find any fine print on the US Airways Club day pass, but I found this blurb regarding First Class check-in and Zone 2 Boarding: "Primary Cardmembers are invited to check in at the US Airways Preferred or First Class counter when checking in for their flight. The Primary Cardmember only is invited to board the aircraft early as part of Zone 2 provided their Dividend Miles number is part of their reservation. First Class check-in and Priority Zone 2 Boarding are only available on US Airways marketed and operated flights." Additionally, if I am flying on an American flight, can I use that boarding pass and my day pass to gain entry into the US Airways Club? Or do I actually have to be flying US Air? Anyone have any experience on this? Thank you.
