If you are a smoker be sure you have one before you go in. No smoking areas once you pass security. **if must,make sure you have some time to spare, you will have to go through security again
Be prepared to wait at baggage claim an inordinate amount of time. It is never timely. Have a book and a cup of coffee. No bathrooms on bagclaim levels.
AT&T service is bizarrely poor here. You'll get a decent signal but speeds sometimes 1% of what you'd expect. Slow, unreliable, paid wifi so download your entertainment before you leave.
If you have a smart phone, save time and paper by not printing out a ticket and letting the security/gate agents just scan the barcode on you phone after you have done the electronic check-in ^_^.
