I'm thinking about getting the US BOA credit card for the access to first class check in and Zone 2 boarding. Could someone who has it let me know if these features become linked to your DM account, or do you have to use the card to buy your tickets? I only travel US Airways for business (usually red-eyes from LAS and PHX to PHL) and use a company credit card to buy my tickets. Also, does this card give you access to exit row seats now that they are locked to status members only.
