  • Terminal transfer and connecting time
    Dec 19, 2013
    1
    I will be arriving from Guatemala City at 4:05 pm on United and making a connection to a United flight to Edmonton at 5:45 PM. Is there enough time to make the connection - 1 hr 40 min?

     

    That will be tough. You will arrive in Terminal E where you will go through immigration, claim your bags, go through customs, and re-check them. You will then go back through security and to your gate which will likely be in Terminal C. It's possible, but your first flight will have to be on-time and you'll have to hurry.

    Hi, if i'm stopping in IAH for 40mins, do I have time totake the shuttle? will i have to go through security again if i do take the TerminaLink shuttle ? thank you

     

    The TerminaLink runs inside security. You do not have to go through security if you need to take it to get between your gates.

     

  • 30 minute layover

    My 17 year old daughter is traveling from Knoxville, Tn to Honolulu on Christmas day. United has changed her flight into Houston and she now only has a 30 minute layover. I believe the Knoxville flight comes in at Terminal B and the HNL leaves out of E. She is not an experienced traveler. Can she make this?

     

    If the first flight is on-time it is doable. All terminals at IAH are connected beyond security by the TerminaLink train, however, if there is an earlier flight, since there has been a schedule change, you can call United and have her moved to that, or you could possibly have her rebooked to connect in Chicago or Washington DC instead.

     

  • Carrier and Terminal Transfer

    I'm From Calgary, Canada, to San Jose, Costa Rica with my connection through IAH. Flying Air Canada to IAH and United from there. I've got a connection time of 61 minutes. Will that be enough time to transfer terminals and check-in with United at IAH? Should I check my bag or take a small one for carry-on?

     

    If your tickets were bought on one reservation (and maybe even if they weren't) your bags can be checked through to San Jose in Calgary as both Air Canada and United are in Star Alliance. If that's the case or if you only take a carry-on, all you will have to do at IAH is take the TerminaLink train from Terminal A to Terminal E, which it connects inside security. If your first flight is on-time you will have enough time.

     

    Hi so if I take the termiallink train from Ato C I won't have to go through security again? thanks

     

  • ORD to GUA via IAH (49minute layover)

    I'll be flying from Chicago-ORD to Guatemala City-GUA the day after Christmas. I have a 49 minute layover at IAH from Chicago to catch my connecting flight to Guatemala City. I am flying United, and both flights were booked on the same reservation. If all goes as planned I will only have a backpack and carry-on duffel to contend with--no checked bags. Is this likely to be enough time to make the connection (assuming no snowpocalypse)?

     

    At IAH, United uses Terminals A, B, C & E (E for international flights). Absent incoming flight's delay, you should be able to make it on time. The above-ground TerminaLink train, which starts its service at the Terminal A station & connects terminals A, B, C, D/E inside security (30 mins transfer from A to D). However, If arriving at gates C29-45 and transferring to Terminal E: walk towards gates C14-24 and proceeds straight on to Terminal E (gates E1-24). Keep in mi that on your return you will need an extra half hour (minimum) for passport/ customs clearance.

     

    P.S. D to E are connected by tunnel.

     

    You will arrive in C and depart from D which are connected directly.

     

    Sorry depart from E (still connected directly)

    We have 2 hour and 15 minute transfer time for our flight from Panama via Houston to Amsterdam. Both flights are opperated by United (both from E terminal). We are very worried about comments and complains regarding the long lines at immigration. We cannot change our flight. Is 2 hours and 15 minutes enough transfertime? Does the airline offers us a later flight in case we would not be able to make it on time?

     

    2 hrs 15 mins should be enough time. There is no later flight from Houston to Amsterdam. If you miss your connection they will either rebook you through another European hub where they may have a later flight or book you on the flight the next day. But again, you should have enough time.

    I have a 38 minute layover and plane change on United in Houston from Indianapolis on my way to San Jose Del Cabo the end of March. Is this enough time to switch terminals and have my bags transferred?

     

    It doesn't leave much time for delays but if your flight is on-time it is enough time. If you arrive in terminal B you need to take the TerminaLink train to Terminal E for your departure. If your flight from Indy arrives in C you can walk to E. All gates are connected beyond security.

     

  • Ontairo, CA to Cancun

    I am flying from Ontario, CA to Cancun with a connection in IAH both ways. When do I go thru customs and is it easier if I only have carry on and no checked bag? I have about a 90 min layover both ways.

     

    On the way to Cancun you will go through Mexican Immigration in Cancun. On that trip in Houston you will just have to go from your arrival gate to your departure gate. On the return trip in Houston you will go through immigration, claim your checked baggage if you have any, then go through customs, then re-check your bag, then go through security and to your departure gate. So yes, on your return trip you will save a little time if you don't check a bag.

     

    How much time is need to go thru customs in IAH from Mexico? With and without checked bags?

     

    Maybe half an hour with bags and a few minutes quicker without. The biggest wait you'll encounter is usually at immigration (the first thing you come to).

    I am looking at a trip with a flight from Chicago to IAH, then with a 43-minute connection time from IAH to a flight to Villahermosa, Mexico. I will have a checked suitcase that will have to be transferred between planes. Will the 43 minutes be enough time? (This set of flights is being offered on the United Airlines website.)

     

    Yes, if your first flight is on-time that is enough time. However, as United only has one flight a day to Villahermosa you will be stuck in Houston overnight if there is a delay and you miss your connection. Since the Villahermosa flight doesn't leave until late afternoon, I would try for an earlier flight into Houston to give yourself more leeway. You will likely arrive in Terminal C and depart from Terminal B which are connected via the TerminaLink train inside security.

     

    Thanks for the info. I note that you preface your comment with "if your first flight is on-time." That caveat is found in many other responses to similar questions, and I quite understand it. But my big, and probably unanswerable, question is, What are the odds??

     

    Since so many passengers are connecting, United does give preference to their Chicago-Houston flights and the weather in Houston is generally good and it isn't congested. Most United Chicago-Houston flights are on-time about 80% of the time.

     

  • I have 38 minutes between arrival/departure from Terminal B to E.

    Does using the same airline helps (United Airlines) from Dallas and leaving to Puerto Rico.

     

    You will have enough time if you hurry and your flight from Dallas is on-time. You will take the TerminaLink train, which runs inside security, between terminals.

     

  • Terminal change with global entry visit

    We have 1 1/2 hours between flights. Will there be enough time to get from C, have our Global Entry interviews (appt is scheduled for 30 minutes after we arrive in C) and then get to our gate in E?

     

    Forgot to include - I estimate the interview will take 20 minutes and we will have to go back through security to catch our flight in terminal E.

     

    That should be enough time.

     

  • Chicago ORD to IAH to Merida, Mexico

    I'm flying from Chicago to Merida, Mexico via IAH. Guessing that flight UA 1421 will arrive into Terminal C or E, and flight UA 1426 will depart from Terminal E. The layover is 2 hr 35 mins. Will I have to go thru security again? Will have 1 carry-on piece of luggage.

     

    Yes, you have the terminals correct. You will not have to go through any security in IAH and you will have plenty of time. Terminals C and E are connected directly.

    flying Vancouver to Huston (united) and onto Ft Lauderdale same day. is terminal E the only one I use??

     

    Make sure to go through U.S. Customs Clearance at Vancouver, saving you time at IAH. United uses Terminals A, B, C & E with corresponding gates (like A11, C29, etc.) Your ticket and the overhead screens on arrival will indicate flight|& gate number. I suggest you open www.ifly.com/iah, then click on 'Terminal Map' under 'QUICK LINKS', and scroll down to the detailed text with transfer information.

     

    Neither of your flights will likely be in Terminal E. Both will likely be in Terminal C. You will pre-clear US Immigration and customs in Vancouver.

     

  • Terminal change from E to A

    I have a connection flight from Houston to Denver with 2.5 hours. The incoming flight is Emirates and outgoing is Frontier. Would this time be sufficient to cover immigration, collection and placing the baggage for next flight.

     

    It will be tight. Your Emirates flight will actually arrive in D, not E. You will have to use the Inter-Terminal Train (which runs outside security) to get from D to A and take your baggage with you unless Emirates is able to check your bags through to Frontier (I suspect that they will not). If they are able to check them through to Denver, then you can drop them at the re-check desk after US Customs. Regardless you'll have to take the Inter-Terminal Train.

     

    Thanks. I got the itenary mentioned as Terminal E. Aplogise for the confusion. So would it be better to consider rebooking

     

    I think you'll have enough time.

     

  • Toronto to San Salvador

    I am arriving from Toronto on Skywest Airlines (operating as United Express) and then travelling to San Salvador on United with a 1 hr and 5 minute connection time. Terminals not assigned yet, any idea which terminal I will likely be routed through?

     

    You will likely arrive in Terminal B. You will depart from Terminal E. You will pre-clear US immigration in Toronto. In IAH, you will have to take the TerminaLink train from B to E (assuming you arrive in B). You will have enough time if your first flight is on-time.
