For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

Plane was packed but flew on-time, and the comfort level was great! All planes are a bit cramped, but the in flight entertainment was superb, snacks were nice, and the crew was polite. Got into Calgary on schedule...all we could ask for

Last minute cancellation, followed by last minute delay with the rescheduled flight. Both due to interval operation issues. Poor resolution.Very disappointing.

On-time boarding, departure, and flight. Electronic notifications about bags for the whole of their own journey too - from when they got accepted into the system through to being loaded onto the plane and then finally being disgorged onto the right carousel. That was an excellent feature.

I am very tall. All airline seats are a bit uncomfortable.

Everything was fine, crew was great. Always appreciate an on-time flight.

Most courteous, helpful employees and all flights were on time.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

No entertainment. Luckily I was the only person in that row. Small seating
