Insights shared by verified travelers who flew to Houston 
WaymonFlew with United Airlines-Jul 2026
Always select seats in 'A' aisle and remember overhead storage is extremely small which required gate checking bags if your carry on is med to large. (Ref to United Airlines.)
PrincessFlew with United Airlines-Jun 2026
Avoid Houston if you have a connection and inclement weather is predicted
Verified travelerFlew with United Airlines-Jun 2026
Flying on Tuesday/Wednesday was the least crowded
CharlesFlew with Spirit Airlines-Apr 2026
Know the Spirit Airlines rules on baggage before getting to the airport. Avoid paying a fee.
DrakeFlew with Southwest-Mar 2026
Arrive 4 hours early During government shut down
Verified travelerFlew with United Airlines-Jan 2026
Night flights are less crowded and leave on time or even earlierike mine did. It was great.
DavidaFlew with Spirit Airlines-Nov 2025
Southwest flies into Hobby, which is closer to the city.
Verified travelerFlew with Spirit Airlines-Sep 2024
Consider one of the non-economy airlines (eg Delta, American) for a more comfortable flight and travel experience.
JoseFlew with United Airlines-Sep 2024
Make sure you have enough time before your next connection. Houston airport is big.
Verified travelerFlew with Lufthansa-Aug 2024
We landed on a domestic flight in C terminal, and had an international departure from Terminal E. FYI, the food and drink selection is better in C, so if you have the time don’t rush to your departure gate.
Verified travelerFlew with Spirit Airlines-Apr 2024
Spirit Airlines is a good and safe, no frills airline. It offers transport for a very cheap fare rate. This is perfect for travelers who can fit all their stuff in a personal sized bag of 18x14x8. Only 1 bag is allowed. If intending to bring a luggage, keep in mind that a prepaid checked in baggage of 40 pounds ($55-60 each way) is cheaper than a prepaid carry on, and it is cheapest when bought together with the fare ticket. Keep also in mind that seats do not recline, so if that is something you need to have especially on longer flights, Spirit airlines isn't for you. So if you just need a no frill, no baggage airfare that transports you from one point to another, Spirit is a reliable, safe and affordable airline to get.
Verified travelerFlew with Delta-Jan 2024
Be early for your flight, curious to the staff, & respect the lavatories; (fellow passengers shares this space with you)

    • Confirm baggage fees and seat-selection costs on budget carriers.
