  • MCO to YYC via IAH
    Jul 6, 2014
    Hi, We will be flying from MCO through IAH to YYC, with a 55 minute layover at IAH. do we need to go through security again at IAH and is 55 minutes enough time? Thanks.


    No, you do not have to go through security again in IAH. The TerminaLink train connects all terminals at IAH inside security if you have to change terminals. You will clear Canadian immigration and customs when you get to Calgary.




  • SAT - IAH - LHR - is 35 mins sufficient?
    Jul 2, 2014
    Hi, I'm travelling from San Antonio to London via IAH. Is 35 mins possible for a connection? This is with United Airlines: UA4561 for SAT-IAH and UA985 for IAH-LHR. thanks!


    It's possible but leaves no room for delays. You will arrive in Terminal B and have to take the TerminaLink Train to Terminal E. If you haven't booked it yet I'd try for an earlier flight from SAT.


  • Connection Cancun to IAH to Vancouver on United
    Jul 26, 2014
    Hi, We are travellign with United from cancun through Houston then to Vancouver with a 1 hr 15 min connection. Tickets were booked together. Will we make it?


    That is very difficult. The minimum connection time for an international arrival at IAH is 90 minutes. You should change your flight.


    Thanks, Just got a notification that they changed my flight time leaving Houston and added on 25 minutes. I think this may work now. Going from terminal E to C.


  • Costa Rica

    I'm traveling from LA on the 3rd and have a 39 minute layover on a flight to San Jose, Cost Rica. Is that enough time. As anyone ever don't this route?


    That is enough time but barely. You will arrive in C and depart from E, which are directly connected


    I am on the same exact flight trying to make the same layover. Hopefully if there are enough people they can hold it a few minutes if need be.


  • PHX to FRA via HOU
    Jun 28, 2014
    My daughter is flying from Phoenix to Frankfurt via Houston. If the flights are on schedule she has 1 hr 5 min at HOU. She will be arriving at C42 and will be leaving from Terminal D. Is that enough time?


    Your transfer time is sufficient: On arrival look for signs to North Concourse, gates C14-23: gate C14 connects to gates D1-D3. (TD has gates D1-12).


  • SFO --> HOU (Term C) --> Panama (Term E)
    Jun 28, 2014
    I have a one hour and 15 min connection between my flight from SFO (Terminal C) and my flight to Panama (Terminal E). Is that enough time and is it walkable?


    On arrival at IAH, at Terminal C (TC), which has North & South Concourses (North gates C24-27; South C29-45) - the South Concourse at gate C45 connects to Terminal E. (follow signs). You have plenty of time.


  • Domestic to International 1 hr layover
    Jun 26, 2014
    I am flying from SAT into IAH (term C)with a 1 hr. layover then going to Toronto YYZ (fromTerm A) is this possible ?


    Yes, it's possible. The TerminaLink connects all Terminals inside security. I assume your Toronto flight is on Air Canada if you say you're leaving from A, correct?


    Yes, thanks


  • Connection time

    I will be arriving at IAH from Santa Ana,CA SNA, at 12:16, United Flight #270 and connect to United Flight 4674 to Grand Rapids, MI at 12:51. Does 35 minutes allow enough time for this??


    Yes, but it allows little time for delays. If you have to change terminals the TerminaLink train connects all terminals inside security.


    Is there a way I could find out the terminals I will be coming in on AND departing from?


    UA270 will likely arrive in C and UA4674 will likely depart from B.


    Thanks for your input.


  • International to domestic in 48 min. Will this work? Security twice?
    Jun 24, 2014
    We are flying from YYC and landing in IAH at 3:30. We then leave IAH towards BHM at 4:23. I know we must change terminals. Will we have to clear customs and go through security before getting to our connection? If so, we won't have time, I believe. Or, can we get from flight to flight without having to go through customs or security? Thank you!


    You will pre-clear US Immigration and Customs in Calgary. Your arrival into IAH will be like a domestic flight. All you have to do is go from your arrival gate to your departure gate. All terminals at IAH are connected inside security by the TerminaLink train.


    Thank you! Is the TerminaLink train the one above ground? I ask because on the way to Calgary, we took the train below ground and it took us out of security (which lead to a needed run through the airport). Thanks!


    Yes, the TerminaLink train runs above ground.


    Thanks!! You have been quite helpful.

    Hi I have booked a flight from SJO Costa rica through CLT on the same reservation,The layover changed and now I have 2 hours to make the connection to charlotte.is that enough time for me?


    its a united flight from sjo to iah and united express from iah to clt by the way


    Yes, 2 hours should be enough time. You will arrive in Terminal E, go through US Immigration, claim your bags, go through US customs, and re-check your bags with United, then go to the departure level and through security. Your flight to Charlotte will depart from Terminal C, which is connected directly to E, or Terminal B, which can be reached using the TerminaLink train inside security.

    We are flying from YYC to Mexico with an 48 mins layover in IAH. Will we have to go through security/TSA before our second flight?


    You do not have to go through Security in IAH. You will pre-clear US Immigration in Calgary. Your arrival in IAH will be like a domestic flight. All terminals at IAH are connected inside security by the TerminaLink train. You should have enough time if your first flight is on-time.


    No, you will not have enough time. You need to change your flights.


    How do I go about changing my flights?


    You need to contact whoever you booked your tickets through (either your travel agent or airline(s))

    Yes, you will have to claim your baggage after immigration, go through customs, and re-check it with United. You will arrive in Terminal E and depart from B or C.
