I know this is kinda a grey area thing with the new terms and conditions. I haven't used a one day pass for a while now but I don't seem to remember them ever entering anything into the computer you could just print out two passes in case they take one and carry a copy of the T&C just to be sure. Last time I tried to buy a day pass at a sky club, I was traveling Korean Air/US Air and had a long ... layover in ORD they wanted to charge me the full rate even though I'm a reserve card holder. Gave me a bunch of crap about only GOld and plat card holders can buy discounted one days passes which is good when you're traveling on any airline. If all else fails i'd email delta and get a few miles for your trouble or maybe another one day pass
