I booked my upcoming trip to Madrid on Delta thanks to the crazy Europe specials that were going on a few weeks ago. I booked MCI-ATL-MAD/MAD-ATL-MCI for $420ai (nothing compared to the under $200 fares, but I'm not east coast). I've always been a huge fan of AA, but I figure this should be good. I'm wondering if there are some secrets that I should know about before I head off in a week. I've already taken advantage of the Delta SkyBonus program and have procured 10 drink tickets. I got an email offering me a 30 day lounge pass for $90. This doesn't seem like a great deal since it doesn't give access to any lounges in MAD or MCI. But. It did get me thinking that lounge access would be pretty nice. Any genius ideas? Anyway, I am pretty pumped about trying a new airline and getting back to Spain. Any tips would be great. Thanks!
