Checking in and departing from IAH:

Terminal C has the most reliably open Precheck and Premier Access security lanes. Consider checking in and clearing security in at Terminal C even if departing from another terminal.

There are no UA check-in counters in Terminal A, even though UA has a few flights that depart from Terminal A. Check in at Terminal B or C.

There is an underground, somewhat slow landside tram system (the Subway) that runs between the basement level of all terminals (plus the on-site Marriott hotel) outside of security. (The Subway was built by Disney and modeled after their PeopleMover ride. It's worth a look if you're into that sort of thing.)

Recommended practices for transiting IAH:

IAH is a huge airport, but all terminals are very conveniently connected by a very frequent, fast airside tram system (the Skyway) inside security. You can pretty much get from any point in the airport to any other point in the airport within about 15 minutes (with a combination of Skyway and a brisk walk) without reclearing security. UA publishes as low as a 35-minute minimum connect time (MCT) at IAH, and while you shouldn't dilly-dally, this is doable on a typical domestic-domestic connection. (It helps if your inbound is not delayed and you're seated towards the front of the plane, of course; your departure flight will be almost fully boarded by the time you get there, but you'll make it.)

Note that the higher-numbered C gates (C29-C45, aka "C South") are directly connected to the E terminal by a walkway. It is usually faster to walk from C South to E (especially the low E gates) than it is to take the train. Similarly, C North (C14-C27) are directly connected to the D terminal, though the Skyway is not really out of the way and is useful if going from a low C gate to a high D gate (C24 to D10, for example). Terminal A and Terminal B are not connected by any walkways, and you must use the Skyway to change to or from these terminals.

For international arrivals: after clearing customs, stay to the left of the baggage re-check belts and follow signs to exit to arrivals (like you're going to curbside). Once in the arrivals lobby, take the elevator or escalator up one floor to find a PreCheck checkpoint and a usually-less-crowded regular checkpoint. If you ignore this advice and proceed up the escalator behind the baggage re-check area, the transit security checkpoint there is often congested and does not have a separate PreCheck checkpoint.

While perhaps not usually recommended, in a pinch, with Global Entry, no checked bags, and PreCheck, it is possible to make a one-hour (or even slightly less) connection by following the above instructions specifically (on a good day, it can take less than 30 minutes from flight arrival to sitting in the Terminal E United Club, as one member reported in the thread). Without Global Entry and with checked luggage (which must be retrieved to go through customs and dropped back off after clearing customs), especially if you are a foreign resident, expect the immigration and customs process to take longer, so allow enough time accordingly. For UA-UA international-international connections (ITI), there is a special immigration line that usually moves pretty quickly, and your baggage will be checked through and does not need to be retrieved to go through customs. No need to collect checked luggage while transiting through IAH. [OneStop]

Again, do not follow signs for international connections up the escalator behind the baggage re-check area; exit to the arrivals waiting area and re-enter one floor above through normal airport security. A map follows for visual learners:

Terminal E arrivals level / departures level:



The marked elevator will spit you out literally directly in front of the PreCheck checkpoint.

Standard UA-UA MCT table for IAH:

 STANDARD.D/D...D/I...I/D...I/I.
 ONLINE .45 1.00 1.00 1.15
 OFFLINE .45 1.00 1.00 1.15
There are lots of exceptions, though, and some specific flights have as low as a 35-minute MCT, which is doable as mentioned above. IAH is a very efficiently designed airport, and you should not worry about what appears to be an abnormally low connection time; if UA says your connection is valid, it is almost certainly doable within the allotted time (notwithstanding delays, of course, and standard advice regarding allowing longer connections for mission-critical travel or travel on separate tickets still stands).

I do know that I need to re-check in luggage at Tokyo but what about Houston Airport?Do we need to go to baggage claim area and pick up the luggage and re-check in at Houston Airport and then head to the gate for the International flight? Or After getting off from the flight UA4339 at B terminal, would we go to D terminal gate straight for the international flight to Tokyo without picking up the luggage for the re-check in?

Thank you
Your luggage will be transferred automatically at IAH.

No worries in Houston so you don't have to leave secure area

YYZ/IAH (UA2357) First
IAH/GIG (UA129) Polaris

Connection time of 1 hour 25 minutes in IAH.
Will have checked bag.
US preclearance in Toronto.

Should I be okay? I don't know what terminal the YYZ flight is likely to arrive in.
I believe the Rio flight departed from C terminal my last trip rather than E.
It's a tighter connection than I like but its an issue of finding a P fare.
thanks IAH experts.

That is more than comfortable connection time. No need to stress.

Could be. Check your bag so you won’t waste time waiting for a gate checked bag to be brought up to the jetway. (term B will be UA Express RJs.).

T-B has three concourses. The older, high high number gates are closest to the Skyway tram. Head for the Skyway, which keeps you in a sterile environment.

The Skyway stop at T-C Is near the low number gates but is not TOO far from the highest numbers.

Hopefully, you’ll be sitting near the front on your inbound and the ground crew doesn’t dawdle getting the jetway up to the plane.

Good luck.

42 minutes is enough time if arrival is on time - that is the key. Skyway runs very frequently, takes about couple minutes to go from B to C, if that, and walk should be no more than 10 minutes in either terminal.

It also depends on which part of B and C you are in. If you land at the NE Banjo B-85-88 and you are flying out of C-teens, you can just walk, it will be just as quick as the tram since those areas are now connected airside. Check the airport map to confirm where your gates are. You will not have any free time but if all is on time you should make it.

Thanksgiving Day is a very slow day. You should be fine.

Getting between terminals E and D during layover

We have a flight from PDX-IAH-CZM with a 3 hour layover. Do we have enough time to get from Concourse E to D to use the Centurion lounge and back to E again?

All IAH concourses are connected airside. You have plenty of time to get anywhere in the airport and back with a three-hour layover.

D and E are connected, all you have to do is walk over roadway - no worries, it's covered and climate controlled.
