We are flying from Cancun to Iah and then to Phoenix with only carry on bags. Both flights are united airlines. Once we land in Iah , will we have to go back thru security checkpoint to get to the domestic terminal? How much time will that take?
Yes, you will. 90-120 minutes is the bare minimum recommended, even without checked bags.
1) if our bags are tagged through to Frankfurt do we still have to claim them in IAH and clear customs? 2) do we have to go through US immigration and passport control even if we are just transiting from Mexico to Germany?
You won't have to claim your bags in Houston but you will have to go through US Immigration, Customs, and Security.
Thank you - we just did that and it worked amazingly! Immigration was fast and friendly. Security was fast and rude!!! Maybe IAH is working on it. We were through to departures in 30 minutes. Not so bad. We landed @ 2.40pm. Cheers
Hi! We'll be going back to Vancouver and this time the layover is around 50mins in DFW. Will the time be enough? We barely made it to our flight coming here because of security and bag recheck in DFW which took more than 1.5 hours. Assuming our plane from IAH arrives on time and there will be no customs or bag recheck in DFW, then we might be able to make it if we're in a hurry; but it would be different, otherwise. Our flight is under the same itinerary. thanks!
What airlines are you flying? Why did you have to claim and re-check your bags win Houston on the way to Dallas? There is no US Customs when leaving the US.
American Airlines... When we flew here to Houston via DFW from Vancouver, we had to do immigration, customs, and claim and re-check our luggages in DFW before flying to Houston. We're just visiting Canada as well so I guess we had to go through immigration in DFW as it is the first US stop that we made on this trip; thus, the immigration.
