Smile and have your paperwork ready! Which airline are you flying in on? Really depends on which airline and terminal.
Believe that is Terminal 3. Just flew in on United to Terminal 3. Not bad at all but long walk from gate to Customs/Immigration. Slso still had green/rec button for luggage. If red have to run through xray and possibly searched. Terminal 4, mainly Southwest is our favorite. Shorter walks snd no red/green button. Customs may ask you what you have, as in cigars or ask where you are staying. They smile when you respond TTR! We have yet been asked to xray bags nor have wr been searched. Smile, be friendly, and look like a tourist going on vacation
March 11th will be our 4th trip and we have vaped by and in the pool every time. Don't tell customs that you are bringing in vape pens if you get the wrong one they will confiscate them.
