Great setup on both flights except the last flight we got condensed dripping all over me in the last 20 mins of the flight

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.

For the amount of money I spent, I definitely expected a better experience

For my third flight in a row on AC 737 Max 8, it was stuffy and warm, especially mid-cabin, Business Class and rear cabin were better. Very uncomfortable 5 hour flight. Do all 737 Max 8 maybe have an HVAC software problem as well or just Air Canada?

The international flights (interior space) is ridiculously small. The aisle way is similar to a discount domestic shuttle. Same applies to the intercontinental flights. The luggage storage space is also incredibly small. The entire experience is rough on a traveler and you pay with your hide and body for not flying let’s say an American or Delta type airline.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

I always had the best experience for the professionalism of the crew and the way they make you feel as a family!!!

Terrible, delayed flights lost luggage and lost hotel fees. Missed meetings. Overnight in airport every air canada flight was a cluster mess.

It was good, seating was a little tight apart from that all was well.

Crew didn’t care at all. Very bad attitude. Food was awful. People changing poop diapers on seats. Very disappointed.

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.

Check-in experience, for business call please provide a premium experience

Getting the boarding passes between the BA and AA apps was very clunky.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.

Very bad. Business class money is paid but service is worst than economy with empty middle seat. Very low grade food, very poor toilet. This should be highlighted as worst business class in the world. Government of Jordan should ban British airways for misleading information.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

It was a good experience, especially travelling with a baby and their accessories

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.
