It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

It was extremely hot in the cabin the entire flight, vent air was worn

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

We were forced to eat vegetarian food because non veg food ran out. The breakfast was mediocre.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

The kid in the middle seat kicked me almost the whole flight, almost kicked my hot tea off my tray. The flight was delayed due to the first plane not being able to be de-iced in July! We had to get a new plane. Now I drive 3 hours back to Edmonton because direct flights from PVR were way to expensive

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

They blocked me from checking in online and they charged me lots of money

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Not have my bag forced to be checked when I had a carry on included on my ticket. Staff was very rude to me for asking why they were doing this. I was told there was no more room for carry ons but there was plenty of space in the overhead compartments

The crew was excellent. What I did not enjoy was the food. I have taken many international flights and this was on the low end. Otherwise the trip was fine.

Seats were the most uncomfortable seats i ever experienced on a flight to Europe from Boston. It was a waist of money in buying premium seats for top dollars. I want my money back for what i paid extra for my seats. Awful conditions!

Boarding felt a little chaotic as everyone was waiting around the gate. Food was great, service was good.

Flight attendants in business class were rather indifferent While in second leg operated by Portugalia TAP subsidiary were outstanfy

The chicken was so dry it was impossible to eat. No substitute was offered. The port to charge my phone was broken and all I got was a shrug from the crew. The entertainment system was glitchy and subtitles didn’t load. Crew seemed fully uninterested and unfriendly.

The flight crew were absolute rock stars. When they came to the gate they looked like royalty, so chic. They also were extremely kind. Food was good and I loved the lack of plastic waste. The flight was lovely and smooth.

Great staff who were ready working with smile 6 in the morning on New Year’s Day. Although security checkpoint was way too busy, the airline staff were understanding and waited few minutes after boarding. We took off not only exactly on time, but arrived 20 minutes early. Two thumbs up!!!
