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:

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).

So I have to check in at IAH Terminal B on Friday very early. I have a 7:21 AM flight. How much wait time can I realistically expect to get through check-in and TSA? I plan to get there about 5:45. Will that be enough time to make it? Should I consider checking in at C instead?
Thanks.
Thanks.

Connection Time at IAH
Not sure I am on proper forum so apologize in advance. I have friends flying United between Springfield, MO and Aukland, NZ. They want to connect to Air New Zealand direct flight at IAH; however, the connection time is only 1hr 6min. They are currently walking a bit slow due to physical condition. I am pretty sure there is a terminal change at IAH. Can they make the connection?

They CAN make the connection, but there isn’t much room for error. The Springfield to Houston plane is a small regional jet that typically parks at Terminal B. From there you take an above ground train to Terminal D. That only takes a few minutes, but when you factor in deplaning, possibly waiting for a gate-checked bag (the ERJ they come in on doesn’t have overhead space for large carry-ones, so they bring them to you outside the boarding door) and any flight delay, it’s tight.

IIRC they can request a cart from UA to get them to SkyWay (train) if they are mobility impaired, not sure about at the other end in D as that is not a UA flight. Maybe NZ can help.
Is this on one ticket or separate tickets? That can make a difference. Is there an earlier flight they can take? If it were me, I would not want to risk an hour connection to an Int'l flight if I could not move well

This isn't advisable for a once-a-day flight that generally has high load factors. I wouldn't do it as a relatively fit person who has occasionally run through IAH to make tight connections. The NZ flight, if on time, will start boarding about 45 minutes out and that Terminal B to Terminal D connection is hard to make in that time.
Decent chance with the change of airlines and terminals that luggage might not make it, even if the people did.
(Auckland, not Aukland, by the way)

Midweek 2:45 pm departure. UA / Domestic / no checked bags / pre-check. How long should I allow to get from rental car center to the gate?

The logistics depend on where your outbound gate is. The last time I flew out of IAH, I entered at Terminal B, cleared security, and took the airside sky train to E for my flight.
T-C can be a real mess with T-E check-in and TSA shut down.
So, regardless of where your plane is departing from, I’d make sure I’m in T-B a minimum of an hour before departure. A little longer if your flight is departing from C or E.

I just did an E international arrival to an E domestic departure and it was super fast with Global Entry and no pre-check at security so that was tedious aspect. Make sure you pick the quickest/shortest line. I only had a backpack with me so it was fast. Make sure you haven't carried any liquids off the international flight, need to dump/empty before getting in line. I never saw any secondary ID checking.

UA domestic flights can leave from any terminal. Although there's no UA check-in at Terminal A, there are enough UA flights that depart from A that there's a United Club there. Also, occasionally a UA flight will depart from D. I had a departure from D18 a couple of weeks ago.

Sure, but IIRC A term is only UAX (not to mention no bathroom in UA Club unless they installed one since I used to fly from there) and D is exceedingly rare except to international flights

UA domestic flights can go out of three terminals. B, C, and E. Check-in at E is currently closed for construction. Which means you have to check in/ go through security at B or C.
The logistics depend on where your outbound gate is. The last time I flew out of IAH, I entered at Terminal B, cleared security, and took the airside sky train to E for my flight.
T-C can be a real mess with T-E check-in and TSA shut down.

Pickups / Dropoffs at IAH During Peak Times
FT Friends,
Does anyone have any hacks for picking up / dropping off family/friends (i.e., non-Uber / town car) at Terminal C during peak times?
I am picking up my daughter (UA DCA-IAH) Tuesday night before Thanksgiving (arrives at 2211) and am considering asking her to just take the "Subway train" to A and meet me there. She is checking a bag FWIW.
We are also dropping her off (UA IAH-DCA) Saturday morning after Thanksgiving.
We have encountered significant traffic issues at Terminals C (pickups/dropoffs) and D (dropoffs) during peak times. Terminal A seems a bit quieter. We have consistently avoided E pickups and instead schlep down to C for those pickups.
I also thought about asking her to take the shuttle to the rental car facility, which seems to have a public parking lot outside the garage. Seems like a lot of effort, but is at least predictable?
Open to ideas!
