How early should I arrive for my flight at IAH?

Travelers are generally advised to arrive at George Bush Intercontinental Airport at least two to three hours before a domestic flight and three to four hours before an international flight. This allowance helps ensure ample time for check-in, security screening, and any unexpected delays that may occur. Additionally, during busy travel periods such as holidays or peak travel season, it may be wise to arrive even earlier to navigate potential crowds. It is important to check with your airline for their specific recommendations, as different airlines may have varying requirements. Factors such as whether you have checked luggage or are traveling with children can also influence how much time you may need.
