My bags were misplaced!!! Im in a foreign country with no bags

Comfort, don't think I will fly United again not worth the money to be packed in like a sardine.

First time flying with UA and it was a great experience. Thank you

All good flight was 35 minutes early when arriving in Edinburgh

Flight delayed. Connecting to night flight was stressful but made it. Jusr in time. Ran.88Flight was fine.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

Flight attendants had a little attitude. Food tastes no good.

Entertainment kept turning itself off. Gave up on watching a movie.

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.
