Best Lounge I have ever seen is the Iberia Lounge in Madrid, Spain. I got in with my AA Platinum status. Spent 4 hours in there of pure bliss returning to DFW. The lounge is huge, has a real restaurant catering the food, a huge spread of delicious food for breakfast, all sorts of drinks, yogurts and other goodies totally free, spacious comfortable, just awesome. THE AA lounge in frankfurt has a decently stocked well bar and beer selection for free and some "OK" food for breakfast (ive only been in the lounges in the morning, don't know how they look for lunch and dinner). I most often sit in the AA terminal D lounge (by gate 23) in DFW, what I like the most is the nice ambiance, awesome bathrooms and showers, the relaxed atmosphere and those huge windows to watch airplanes come and go.......
