Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Everything was on time and service on the flight was great!

The boarding in Buenos Aires (at the on ramp) was not great. They had to check every carry on. Not a United problem but was a Buenos Aires problem.

Staff and aircraft were good. However, weather in Houston lee to a ground stop. We were looking at circling behind three other planes until the stop was lifted. Pilot said we didn’t have enough fuel for that. So we flew on to New Orleans as the closest port with immigration and customs staff. Landed there and sat in the plane for two hours plus while staff was sorted. Turned away by ICE. Waited for pilots to be switched out, but after they were approved by ICE. Then had to wait to get a runway because so many planes were ahead of us. Finally took off and flew back to Houston. We all missed our connecting flights because it took too long. Hotel voucher from United was only a link to booking site. Total BS. Finally got a flight out the next day after a night without sleep because all the Houston hotels were booked by rodeo and spring break crowds.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

Complimentary light meal would be appreciated. But great flight crew service on all legs

Crew was tired as we all were. Pretty abrupt. Flight was delayed. Not as enjoyable as the other 3 legs we flew.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.
