✈️ Flight Guide: Houston (IAH) → San Francisco (SFO)

July events can drive higher demand and fare spikes between George Bush Intercontinental Airport (IAH) and San Francisco International Airport (SFO). In Houston, July 4th celebrations (such as Freedom Over Texas in previous years) and summertime concerts can increase outbound travel.

If traveling during July weekends or around Independence Day, book flights and hotels early, and expect heavier traffic to and from both airports. CTA: Check event calendars for Houston and San Francisco before finalizing your July IAH to SFO itinerary.

For July travel on the IAH–SFO route, the best times to fly are early morning departures (06:00–09:00) on Tuesdays, Wednesdays, or Thursdays for a combination of lower fares and improved on-time performance.
