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.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Delay was not properly communicated. Service, plane, value of ticker were all great.

Excellent service and food in the Club Class. Warmly recommend. Much better than AC.

My new suitcase got busted when I arrived at Toronto , two of the wheels are broken and can no longer be used , I am very disappointed over this situation but the flight and service was awesome .

The flight attendants were lovely - very warm and kind. Really appreciated it.

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

eveythink, because of you I lost 100 euros for my train connection

There was a terrible delay upon arrival in Barcelona. The plane had to park a great distance from the terminal, and only one bus was available to make the ~15 minutes each way trip, meaning it was ~ 45 minutes after we landed that I finally entered the terminal.

Cold frozen fruit for breakfast was unexpected and a waste in my opinion. How about a warm bun would have been better. Otherwise great on time flight.

I used to enjoy the travelling experience, but no more. We pay more and get much less. No air travel for me on the near future.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

The Q400 plane is getting old and very noisy. They should allow the quieter jets fly onto the island.

Both my flights from Calgary to Montreal were pleasant. I should also mention my gratitude to the two ladies at YYC who helped with my check in and went out of their way to assist me.

It got me from A to B in one piece and in good time. Back of seat tv didn't work. Snacks are a joke

This was a HORRIBLE experience. I booked a two-leg flight from Reykjavik to Istanbul. My first flight ran 3 hours late and I then missed my flight to Istanbul. British Airways put me on a Turkish Airlines flight to Istanbul. No harm done, right? Wrong. The Turkish Airlines flight turned out to be overbooked. By the time I learned of this, British Airways closed their help desk. To add insult to injury, they helped one person in front of me before casually putting up a closed sign even though they knew I was stranded (their fault!) and needed help. I ended up spending $1000+ out of pocket to clean up their mess (including the flight to Johannesburg I had to rebook since BA delayed me so much) and haven’t heard a word about reimbursement. I have never had such an awful travel experience in my life. I know delays happen, but they need to take care of their passengers when these things happen, not leave us stranded in a foreign country in the middle of the night with nowhere to go.

The seats are incredibly uncomfortable. My luggage didn't make it on my flight from London to Nashville.

5 days later I have not yet received my luggage so terrible and unacceptable

everything on the flight was a great experience except the food could have been better!

The seats were uncomfy and the food tasteless, crew clueless

Easy and quick check in, clean and nice seats. Overall excellent experience.

My problem was with the onward connection between London Heathrow and Washington IAD. The flight was several times changed.

The A350 is a great plane but BA's seating was incredibly tight (eg compared to the same plane as flown by BA's partner Finnair) and with a middle seat it was very claustrophobic

Flights were on time. Crew was courteous. Food was much better than I expected. Heathrow is a good transit hub - great selection at the duty free.

The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.
