The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

Extra attention to kids, thank you, we appreciate! Perfect landing

Over the wing seat at emergency exit only downside people using lavatory have no respect and wait in the space

Flight delayed any hour and couple of big gate changes

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

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.

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.
