Currently, the TSA wait times at Houston George Bush Intercontinental Airport (IAH) are concerning.

Reports indicate that wait times at nearby Hobby Airport have exceeded 3 hours, and the situation at George Bush Airport (IAH) is not much different.

The main reason for this is an increase in absences among TSA staff due to wage issues, leading to a reduction in the number of personnel operating the checkpoints.

If you have upcoming travel plans, it is essential to be aware of this situation in advance.

IAH has terminals ranging from A to E, with 6 to 7 TSA checkpoints distributed throughout.

Terminal A has two checkpoints (North and South), Terminal B has one, Terminal C is divided into North and South, and Terminals D and E are exclusively for international flights. Even at the same airport, the wait time can vary by over an hour depending on which line you enter. If you enter through the nearest entrance without knowing this, you may end up waiting longer.

Currently, the busiest areas are Terminals D and E. This is due to the concentration of international arrivals and overlapping times with connecting passengers. Next is Terminal C North, which is where the demand for United Airlines domestic connections is concentrated.

In contrast, Terminals A and B are relatively less crowded. Since IAH has internal connections between terminals, if you have time, it is practically advantageous to move to a less crowded terminal checkpoint. Asking a staff member for the "faster checkpoint" is also a good strategy.

If you are arriving on an international flight and transferring to a domestic flight, there is an additional process. The sequence is: immigration (CBP) → baggage claim → customs clearance → rechecking baggage → TSA recheck. You will need to go through TSA once more in this segment, and you will be automatically directed to the connected terminal checkpoint.

During peak times when international arrivals are concentrated in the morning and evening, this segment can take over an hour. If your layover time is tight, it is safer to check with the airline in advance.

Since the situation can change frequently, it is essential to check before your departure. The official Houston airport website fly2houston.com/iah/security provides real-time wait times for each terminal.

The official TSA app, MyTSA, is also useful. It allows you to view real-time and estimated wait times at airports nationwide.

If you are flying internationally, aim to arrive at least 3 hours before your flight. However, arriving too early may result in unnecessary waiting at the gate, so it is wise to check real-time data and adjust your departure time accordingly.

If you have the budget and frequently travel domestically and internationally, I strongly recommend enrolling in TSA PreCheck or CLEAR. TSA PreCheck costs $85 for 5 years and allows you to use dedicated lines.

CLEAR, which is the most expensive option, costs about $200 per year and allows you to skip identity verification using biometric technology. If you have Global Entry, which costs $120 for 5 years, TSA PreCheck is automatically included.

At busy airports like IAH, this one card can save you time. When you convert the time and stress spent in security lines into money, it is definitely worth it.

IAH is a large and complex airport. Understanding the terminal layout, checking real-time wait times, and avoiding peak hours can significantly change your experience. Many travelers miss their flights due to a lack of information, so it is best to gather as much information as possible in advance.
