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.

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

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 good. I wish you had gluten free snacks for my husband.

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.

It isvvery small flight. No leg room . No space to put my personal item at feet.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

Apparently the WiFi you buy on on one flight doesn't carry on with connecting flights.

Once again, flight was delayed from Houston to ELP by three hours. The last two-three times were flight crew scheduling issues causing significant delays and a stay over. After traveling internationally for business and needing to drive an hour home after landing close to midnight, this is an unsafe situation when exhausted. United has went from a preferred airline of mine to one of the worst due to reliability. As someone who had to get a new passport because I filled it up pre-pandemic, I still ONLY travel because I have to and not because I want to (leisure) because of the consistent subpar experiences. The United lounge closed at 9pm, so we had to sit in general boarding without working power outlets. Thankfully, the lounge had excellent service, abundant quiet space, and improved food selections.
