This airport has a few OMA Lounges. I have not seen the other two but the one found in Terminal A is very nice. It's on the smaller side, but that's okay because it'll never get too crowded. It was quiet enough to nap in, and if you can grab a small couch you're layover will be very comfortable.
The complimentary appetizers were delicious! We grabbed a few beers, snacks, mooched off their wifi, and got to chill in an immaculate lounge. It was very clean, and smelled fantastic! The staff was nice and polite, but I did wish they would smile a little. Gratuity is not expected at most lounges. It depends on the location and since Mexico is a very gratuity based culture, I recommend tipping a few dollars if you feel like it. I saw plenty of sockets around to plug into. My only suggestion would be I wish they had more than one restroom available for men and women, but check it out if you have the time! read more
