Shift your dates by a day or two: Mid-week departures (Tuesday–Wednesday) are almost always cheaper than weekend flights. Even shifting by one day can make a meaningful difference.

Weigh up connecting flights: Connecting flights on Los Angeles to Houston can be 20–40% cheaper than direct options. If you have time to spare, it's worth comparing.

Factor in baggage fees: Low-cost carriers on this route often advertise attractive base fares but charge separately for checked luggage.
