Very Good|Apr 2025

Baby in front of me cried throughout the flight.(This was beyond the crew control) A flight attendant that decided he wanted to have continuous conservation with the passenger also in front of me. Considering it was a night flight it was literally painful. Thank you

Poor|Mar 2025

Plane was delayed 2 hours. We were charged extra for luggage and seats. Seat rows were so close together that it was almost impossible to get in and out to use the bathroom, let alone sit comfortably. Food was mediocre at best. Your ambient music is the same tune that is used when AA puts me on hold. Flying has become a nightmare!

Poor|Feb 2025

My wife bought tickets using her married name, but forgot her passport was still in her maiden name. We were denied boarding and had to cancel our trip - no refunds - the company would not simply change the name on the ticket. It is just wrong to do that to someone like her.

Wonderful|Feb 2025

After flying on easyJet and Ryan air frequently over the last few years was nice to get back to an airline that was on time and valued its passengers. We will be back !!
