We sat at the gate for over 30 minutes, with no indication as to why

I didn't really interact with any of the crew since we had a bumpy ride and no refreshments were distributed.

Great. No issue.

2.0 Poor

Javeon, Sep 2026

It was delayed over an hour and a lot of announcements disrupting movie.

6.0 Okay

Anonymous, Sep 2026

My flight experience was generally good, but the boarding process was stressful. I was pulled out of line at the gate during the photo ID check, and after being cleared, I was never given an explanation for the delay despite asking for clarification. This lack of communication was the only downside to an otherwise smooth trip.

6.0 Okay

Anonymous, Sep 2026

I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

10.0 Wonderful

James, Sep 2026

Loved tvs and the plane and the staff

4.0 Mediocre

Rick, Sep 2026

Seats were old and very uncomfortable. Coach seating is way too tight

6.0 Okay

Gopal, Sep 2026

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience
