Leaving from Los Angeles (LAX)
Plan to be at the airport two hours before a domestic departure — ninety minutes can work at smaller airports outside peak times, but security lines are the one variable you can't control. If you're checking a bag, add time rather than cutting it close. Our Los Angeles airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in Houston (IAH)
Before you land, know how you're getting from the airport to where you're staying — it's the part of the trip people forget to plan. The Houston airport guide lays out your ground options, from transit and shuttles to rideshares and rental cars. Flying back the other way? Check Houston to Los Angeles fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 1,376 miles, booking 3–6 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
