Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We had an unfortunate experience where we had to leave the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason given was that a passenger felt ill and had to cancel their plans and therefor their luggage had to be found and removed.

We’ve used VA before many times the experience is always been good they have lovely staff and the food is always delicious.

Everything about the flight was amazing from check in to boarding entertainment was okay food we didn’t try.

Not the greatest experience everything was pretty mediocre. My seat was by the washroom in the aisle and was not located well as everyone past each other people were right in my seat and space.

Lots of overhead storage, good crew, good service, smooth landing.

Lots of overhead storage and a good crew and service.

The small prop plane was crowded and the overhead luggage storage is a smaller than on the jets. Other than that, the crew was good, the flight was on time and the landing was smooth.

There was a medical emergency that the crew handled very well. There was no “entertainment” of any sort-no movie/music/whatever. Food was typical of airlines: mediocre.

On time. Friendly and efficient staff at check in and flight crew.

Terrible decision to take a night flight. Not enough time to sleep and premium seat has no foot rest ao couldn’t get comfortable!

Late departure, so I missed connection in Detroit. But Delta gave me a great hotel & breakfast. Just sorry I could not get anything from my checked baggage.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

Was on a Swoop plane. No wifi and no Westjet connect

Food hope it make it international not mainly like pilipino food

Just a little improvement on food but everything is excellent

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport

This was actually a bus ride to the KW airport. It was smooth and comfortable and on time.

The plane in use lacked an entertainment system (perhaps because it was still being updated?). It was an overnight flight so it wasn't terrible but still. The actual seat was adequate but not great. As an economy flyer, food review is largely irrelevant. I am unhappy with this race to the bottom for services provided especially as it applies to baggage restrictions.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

Good flight, friendly crew and overall - good service on United Airlines.

Enjoyed the flights with Air Canada. Friendly, courteous staff and flight crew - kept us informed and efficiently got us boarded and to destination on time. Seats were reasonably comfortable and good room in the overhead spaces.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

In flight WiFi not working. entertainment system not functioning Food was mediocre poor for business class Service was ok but not excellent Crew were pleasant. Announcements were made at a ridiculous volume.

Everything well done and customer oriented There entertainment system is difficult to navigate

Smooth Flight, Friendly crew, food offering on board was limited.

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

All was good. I would have preferred free drinks besides water (coffee/tea).

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

The payment system was not working so was unable to connect wifi the entire flight

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

The crew did not really interact with me which was no problem as I was fine. I did see that they were somewhat short with some passengers but that was not common. Just in general, they did not seem friendly - no requirement to be so but I am used to a friendly crew on most flights. The food was just ok but with a flight that large, I would think it hard to make something more elaborate.

Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.
