An odd thing to me about changing flights in T2 was that there were different security lines for domestic and international passengers even though they feed into the same departure hall. Maybe international security is more thorough. The international lounge is a smaller version of the domestic. They are both on the mezzanine, but at opposite ends of the catwalk. Use the domestic if possible. It's better. It's the one with the wine bar which also serves sushi. If you plan on a glass of wine in there, prepare to pay muchos pesos. The self-serve bar is free with fairly good quality offerings. However, the only wine, white or red, is Chateau Domecq. The white was the worst wine I have ever tasted.
