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 .

From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

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

I have flown on many airlines all over the world, and this plane flight was the most uncomfortable I have ever experienced.

Flight from Minneapolis to Montreal was easy, breezy. Small plane, so not much overhead space. The seats felt slightly smaller than normal, but not uncomfortable for my body type. No screens in the seats for watching movies or shows, but I don't mind, I'm more of a reader.

Great job notifying of 30 minute delay in departure. Fabulous job making up for the time and arriving as scheduled. Air travel is just no fun anymore with the extreme overcrowding, and someone needs to come up with an innovative plan for loading and unloading passengers (load all window seats first, middle seats second, aisle seats last?). Great job getting the luggage on the carousel in record time!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

Our headphone plug in was broken, especially we are with 5 years old who like to watch a movie

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

App totally screwed me up trying to check in. Would not let me select a reasonable seat and therefore I was stuck in a totally uncomfortable seat for 7 hours. Will not take the chance again and use other airlines in future where no issue choosing seats

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

Not being stuck in the middle seat between strangers but that’s not the airlines fault

On board was excellent—a remarkable positive change. Check in was horrifying. Forced to check in branded cabin baggage approved bags weighing 10 and 12 kgs each, because desk insisted these were not fit for overhead lockers. Got charged £160 for two bags. Behaviour of staff was hostile, motivated and rude. Wonder if BA pays commissions on collection, or borrows staff from Airport operator. Basle evidently is an airport used by budget airline— and customers are treated like consumers.

I was at the airport 10 hour early. I would have loved to drop luggage in advance but this was possible only 3h before the scheduled time, however BA was so kind to move me to the earlier flight as it had space available at no extra cost. Thank you!
