Delayed for 3 hours- little to no communication about this and staff moves in slow motion

Nothing, they could have made some accommodation for an awful experience. Me and my family were not informed properly we we separated. They took me off the original flight i booked. I booked our flight at one price and called me and told me they were not honoring my rate and they charged me double of what I paid. Me and my family don’t want to ever use your services again.

Better movie and tv selections. Also, the overnight flight to Trinidad from Toronto, the staff were not very attentive. I did not see them for at least half the fight. They were behind their curtain a lot of the time, and they did not check on us before landing to make sure all landing requirements were met.

I liked the extra leg room in Caribbean plus. Worth the extra money. The food could have been more balanced, there was no salad or veggies

The Flight itself was smooth and uneventful. The crew was polite and caring. I used the Lounge in Piarco and the service was STELLAR

Music would have been great and information about the flight. Meaning how high and the weather conditions.

I enjoyed the smooth flow and well coordinated boarding and the very courteous attitude from the cabin crew We look forward to flying with ya’ll again

The crew was excellent, check in was easy ,the food wasn't good, movies should be recent and more selections

The captain was great he made jokes and make thebflight very comfortable. Alerted us about the islands we flew over and Yolandra and her team took great care of us, very personable.

Checking in was seamless Flight left on time Flight arrived 45 minutes ahead of time, Overall, it was a good experience
