Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

I’ve wasted 7 hours of my time because of the delayed. ;(

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

Overall great. The crews were lovely. The seats are awful. I always emerge with a back ache.

I liked the behaviour of the crew members.The flight was good.

Would like whole can of pop for 2. Treats were not great . The garlic pretzels were terrible for someone who can't eat garlic. Passenger was 84.

I had boarding pass on my phone. Husband and I were seated together. Agent printed out boarding passes and we were separated for the flight

1 hour late No hot drinks No restroom in the back of the plane

You was on strike and I had to get another r flight and you did not give me my money back

Food can be better. Taste and option, the pasta wasn't the greatest.
