Flying from New Orleans to Houston: what you need to know
The flight
At 304 miles, MSY to IAH is one of those quick up-and-down flights: roughly 1h 7m nonstop. There's no meal service to plan around — the decisions that matter here are departure time and which airport entrance traffic is kinder to you.
Airlines on this route
United Airlines flies this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another. Checked-bag fees, free seat selection and change rules all differ, so compare the full trip cost before you pick a winner. See our airline guides for exactly what each carrier charges — then send an enquiry and we'll confirm the all-in price for your dates.
Leaving from New Orleans (MSY)
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 New Orleans 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 New Orleans fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 304 miles, booking 2–4 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.
Good to know before you go
- Nonstop time on this route is about 1h 7m — a one-stop itinerary needs to be a lot cheaper to be worth the extra hours.
- Tuesday and Wednesday departures are typically the cheapest days on domestic routes.
- Screenshot your fare before you enquire — prices move, and a saved fare helps our team match or beat it.
- Flexible dates? Search a few days either side — one day can change the fare a lot.
- Morning flights are delayed less often than evening ones — earlier departures have the best on-time record.
