Don't buy business class. It"s a relatively short day time flight. and not worth the extra expense. Stick with premium economy.

They are super strict on carry-on size and weight. I have never seen an airline weigh a carry-on before. If you are flying through Germany, make sure to alott yourself extra time to stand in a giant line for a passport check, even though it was already checked when boarding to Germany (not sure what could have changed with it during the flight!). They had given some of our seats away on our connecting flight because we barely made it to the gate in time for departure.

Avoid Frankfurt and O'Hare if you can. Use Amsterdam as your European hub and Minneapolis or Dallas as your hub in middle America.

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.

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.

They never clean the toilet, and the food is worse

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Chargers didn’t work, no entertainment and we had to wait for taxiing for easily 40 minutes after arriving early. Bags were late too!

No real complaints. The in flight food was much better than I expected. The in flight entertainment was excellent.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Horrible Flight significantly delayed. Not due to united issue. But trying to rebook connection flight and get information about overnight accommodation was difficult. Agent did not seem to care or have any interest to help.

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

This Japanese airline provides great service and very helpful in assisting their passengers.

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.
