United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

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

Terrible experience! delay 2 time and say i dont have ticket

Both my flight where delayed Had 25min to make it to my transfer flight

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

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.

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .
