Best places to work at George Bush Intercontinental Airport

Best for laptop work

Terminal D is usually one of the best public-terminal options at IAH for laptop work because it tends to offer broader waiting areas and a more comfortable layout for longer dwell times.

Best for calls

For short calls, quieter edge seating and calmer waiting areas usually work better than the busiest food courts and gate clusters.

Best near power

Gate-adjacent seating, larger waiting areas and counters are usually your safest bet if you need both a seat and nearby power.

Best backup Wi-Fi

If the Wi-Fi feels crowded, moving away from packed boarding areas and into calmer seating zones usually improves the experience.

Best food + Wi-Fi combo

Food-adjacent seating works well for casual use, but quieter counters and broader waiting areas are usually better if you need to stay productive.
