What You'll Learn
International flights: arrive at least three hours before departure
For international flights, it is recommended that you arrive at the airport at least three hours before your scheduled departure time. This is to ensure that you have enough time to check in, drop off your luggage, and go through security and immigration.
Checking in for your flight can be done online a day ahead of time, which will save you time at the airport. If you are checking your luggage, you will need to allow extra time for this process, as the agents will need to check your passport and any required travel documents, such as visas. This can sometimes cause delays, especially during busy travel seasons or if there are unexpected lines or other factors.
Upon arrival at IAH for an international flight, passengers will disembark and make their way through secure corridors and sky bridges to the Federal Inspection Services (FIS) area. Here, they will clear immigration and passport control, go downstairs to level one, claim their baggage, and clear customs. It is recommended to have the necessary documents readily available, such as a customs declaration form or Global Entry kiosk receipt.
The time required for the check-in process at IAH can vary. Some travellers suggest arriving two hours before an international flight, while others recommend adhering to the suggested three hours to start your trip on a positive note and avoid any last-minute rushing. Arriving early also allows for potential delays due to weather conditions or other unforeseen circumstances.
Additionally, having TSA PreCheck approval or a Clear Card can expedite the security process and reduce waiting times. If you have global entry, the customs process at IAH is reported to be quick, taking approximately seven minutes. However, the longest part is usually waiting to collect the checked baggage.

This is especially important if you are checking bags, as the check-in lines can be slow, and you may need to allow for unexpected delays.
Arriving early is a good idea, even if you have checked in online, as you will still need to drop off your luggage.

This process can take longer if you need a visa or other documentation.

TSA Pre✓®: speed up security checks
It is recommended that travellers arrive at IAH airport two hours ahead of their flight time. This is because the check-in line is where things usually slow down, with some travellers taking up to twenty minutes to check in.

TSA PreCheck® is a service provided by the Transportation Security Administration (TSA). It allows members to expedite the security screening process at the airport.

About 99% of TSA PreCheck® passengers wait less than 10 minutes to clear security.
To become a TSA PreCheck® member, you must be a U.S. citizen, U.S. national, or lawful permanent resident. You can enrol online or at any enrolment location. You will need to provide certain documentation, such as proof of citizenship and a valid form of identification. It's important to note that even with TSA PreCheck®, no individual is guaranteed expedited screening. The TSA uses unpredictable security measures, both seen and unseen, throughout the airport, and all travellers will be screened.
