Get the breakfast tacos or burrito at panchitos in terminal B. Ask for it fiesta style and they'll throw on sauteed peppers and onions, no extra charge!
If you're flying out terminal A south concourse, there is no lounge & no wifi. The food choices are terrible; McDonalds, Starbucks, UNO pizza, Tex Mex, Chilis. Bring your own food & a book!
Travel a lot and deal with "normal" air travel problems often but I will avoid IAH always (awful layout, long lines for help, of course humid and, though friendly and caring, no REAL help given).
Terminal A is pretty miserable. No TSA PreCheck line. You have to go to Term C for that. No Delta Lounge. You have to use the KLM Lounge in Term D. But the tram gets you to/from terminals quickly.
Not amusing. Limited cafés, below average duty free with limited variety of souvenirs and etc. Announcers mumble not aware this is an international airport and not everyone is Texas born. Free WiFi.
Sometimes, an elite security checkpoint is open on second floor of terminal C. But not after 4pm on thursdays, as I and 100 of my closest friends just found out.
Huge airport! Be prepared to take a tram if you are connecting flights. Don't recommend making layovers less than an hour especially as several carriers have poor on time records.
Make sure you have the newest passport version from your host country. Even if your Canadian ...smh. Spent 15 min with literally 5 diff ppl looking at my passport. #lackoftraining
