Eventless. It was a good flight and good crew. Can’t complaint.

Seats were roomy. Lavatories were surprisingly big and clean. Plenty of entertainment available. We were fed and offered drinks, multiple times during the flight.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

rushed onto the plane by inpatient staff just to sit on the taxiway just want to add, the flight out of Philadelphia and into Fort Worth Texas was terrible. canceled twice because of non-existent weather, and delayed.

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

First class flight attendant was rude and lacked any customer service skills.

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Almost no food given on a 5-hour flight (only a cookie, which is almost a joke). Boarding was a mess (as always, in Montreal boarding by zones is chaotic and the lines are a total mess). The entertainment system was old and with a limited selection.

Very nice comfortable spacy Airbus 321. I liked the offer of food on the Bistro menu. The idea is very good to pay and cost was low.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.

Staff was very attentive! Food was good for premium economy airplane food. Clearly an older plane - seat back had to be pulled up manually after being reclined.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

No frills very ordinary, charged me twice to book my seat assignment will.need to complain for reimbursement.

Everything ok, but it was a lot of turbulence during the flight.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand
