from domestic to international is a long walk, if you can make this short cut is better, i had a surgery so having a hard time to walk
SharonFlew with United Airlines-Oct 2026
Arrive at the airport at least two (2) hours before departure. TSA in Houston was a chokepoint.
SandraFlew with United Airlines-Oct 2026
Pay attention for gate changes. Very large airport and easy to get turned around.

Usually, bags come out at LAX on baggage carousel #1 but it has happened several times they switch at the last minute to another.

AgustinFlew with United Airlines-Feb 2026
Arrive early for your flight so you’re not rushing. And have plenty of patience with other people that are impatient.
DavidFlew with Air New Zealand-Jan 2026
Very limited space for carry on bags. Most had to be put with checked bags. Be ready for that
WaleFlew with United Airlines-Dec 2025
Make sure your electronics are charged before boarding, the plane doesn’t have power outlets
LaneFlew with United Airlines-Mar 2025
Fly out of Houston Hobby right now. All the construction going on at Houston Bush makes arrival and checkin a nightmare. Almost every flight must checkin at Terminal C regardless of what gate/terminal you actually depart out of. I missed this note on the United app and took 2 elderly people traveling with me to terminal A to checkin and had to lug them around the subway underground to get back to C and that took forever.
Verified travelerFlew with American Airlines-Feb 2025
If you have a connection flight check the monitors, the gate will more then likely change.
AlcideFlew with United Airlines-Nov 2024
Lafayette has received a big update so the airport is great now. Just prepare for weather related delays.
SamFlew with Southwest-Sep 2024
Easy flying with Southwest, Hobby (HOU) and San Antonio (SAT) airports are small and easy to navigate.

Tru and get a direct flight through United or Alaska so you have no transfers!!!

It’s too cold like fridge and they don’t offer a blanket with expensive price

Horrible communication from Southwest. No accountability. Flight was delayed for 4 hours and TSA closed in the interim. We were not allowed to our gate. Southwest knew this information and did not relay to their customers to arrive to the airport earlier.

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

My experience was find with Southwest. The only issue I have is...at the exact time for me to check in...I don't understand how I always end up in C.

Very helpful, convenient, nice crew members, no extra fees, helped us saving 4 hrs of travel by booking is on an earlier flight

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

It was a very good experience. No major issues at all.

On time, quick boarding, so nice of them to honor active and retired military with early boarding. Attendants were nice . Plane was clean. A bit crowded like all flights.

Everything was great except the fact that catering did not restock the flight from ATL to GRB and we were only offered water.

The WiFi on the plane was out. I also thought movie options were lacking.

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

My seat was changed without my consent. It wasn’t a major deal but annoying.

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

bulkhead seat had very little legroom - even in bsiness class.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

Seat would not recline, and charger did not work. Person in front of me reclined before we took off and left it reclined when they got off the plane. Nobody ever told them to put their seat in upright position....which meant I was somewhat trapped in my window seat when deplaning. Another passenger had to go to their seat and un-recline so I could get out.

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

I couldn’t give an honest evaluation, because the Houston airport has a problem and I was stand up for several hours and after a long trip from Munich I feel really very tired

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Good flight, even though there was a delay, still got back on time

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Platinum status. 65 people in the upgrades list. When everyone is special No one is

Great for a small Commuter. Quiet and relaxing. Seats were better than most.

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Was as expected. Good leg room on planes - much appreciated.

I know that there is nothing than can be done about rude customers. I did find a couple of them were very rude and inconsiderate In my case the guy who was sitting in the same row as I was in, was trying to watch a movie with no headphones, a crew member did ask him to turn it down or off (thumbs up for that.) Another thing, as we were about to land another young man must have taken his phone off airplane mode was talking with his friends and using fowl language which I found inappropriate to the ppl who were sitting in the same row as him and other ppl around him. I understand how no one wanted to address this person and not get involved. We all just wanted to get home safely with out any incident.

We were delayed three times ,and that destroyed my plans, and reservations

The reps working at the airport counter were dumber than a second coat of paint.

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

Airline changed the gate from Terminal A to Terminal D which is quite far and only sent a text message few minutes before boarding. Around 50 people missed their flight and as plane didn’t wait for them.

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

Well I mean u get what u pay for so 🤷‍♂️

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

Flight delayed an hour. The turbulence was insane. Packed in like sardines. A coke was $4.95 no snack or a drink crazy
