Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

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.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress

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

No seat back entertainment. And app had a hard time getting entertainment loaded.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

Staff on board was excellent. Positive upbeat helpful- like it used to be.

United has come a long way, it’s been a fantastic experience traveling with them.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Staff was rude. Didn’t give water for 2 hours. Worst service

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

It’s a service to take you from one point to another. No frills. You want it, you take it. It’s upon you to bring food, reading material, games to play, movies to watch, etc. The wifi onboard never works - so you cannot even listen to any podcasts, music, or get updated news feeds. The toilet is a mess, and a four flight does not need any hygienic interventions when people either splatter their pee all over the seats or on the floor. It’s a monopolized service and so smile and bear it.

Broke my luggage and I can't get a resolution yet.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

The flight was good. The only reason I did not say “excellent” was the delay

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

Ground crew forced me to double pay for infant international charges, when I complained about this and told them, with proof, I already paid they threaten to not allow me on the plane because I was “being rude”. Horrible ground management, horrible airline.

They are offering less and less for more and more. They changed our seat that we paid extra to select at the last minute. The seats are way too narrow and my elbows went numb.

great flights both ways on time both ways.staff(ladies) where great at check-in.

We travelled from London to Halifax. Customer service was excellent.fron the day we booked until arriving. The gate was only a short frombthe waiting area and walk Boarding was efficiently handled and plane took off on time. The service on the plane was very good. Fool an acceptable drandard Only downside was that the legroom was tight for anybody just over 6ft tall and am usually able to travel without difficulty. I will definitely fly with Air Canada again but next time pay for extr space.

No entertainment system. Paid extra for wider seats but not worth the cost. Flight left a little late and arrived early.

Flight left on time. Crew was polite and helpful. Flight arrived early at destination. Had some trouble with in-flight entertainment system (not built in to seat-back) but found a work-around. Good experience.

The crew assigned did not start on time due to delays on having a person call off sick and later having a person not wanting to stay on cancun. No screens and also no beverages provided delay for 2 h 15 min

The 6 hour delay with minimal updates was not handled well. After many complaints from most of the un-boarded passengers, food vouchers were offered. The catering strike meant there was no food or snacks on the plane. Beverage service was heavily impacted, only water or juice was available. The staff at the gate was kind enough to inform that "if you want to eat on the plane, you will need to bring it on when boarding".

I did not like the fact that our bags went missing

Boarding was seemless. As for the flight itself, we deiced the wings twice. Had to come back to check for mechanical issues leading to our flight arriving 3-hours late to destination. As for food choice, do not choose the pancakes as it was similar to eating sweet microwaved porridge.

The landing was a little rough fit the size and weight of the plane we made it .

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I couldn't get a vegan meal because I booked via kayak but everything else was lovely

BAD!!! due to delay I missed my connection in MEX, had to pay for hotel and new flight for next morning increasing my spent for $1,000 usd

Aircraft delayed for two hours due to a technical issue with the rear emergency exit door slide not working.

Superb staff, ingenious seating in Club class. Superb food and service. Loading and unloading. Ample cabin overhead luggage space. But the earphone socket was damaged and did not give binaural audio. Very hard to follow a film over the engine noise. Nor could I get to play Sudoku for want of instructions.

The plane seemd untidy and old. Ran out of food and drinks
