The flight crew was extremely hospitable, though there was a lot of turbulence, they made it a good experience. The only negative was the inflight experience for economy class. There wasn’t any, or at least non that I was aware of.

The flight crew was extremely hospitable, though there was a lot of turbulence, they made it a good experience. The only negative was the inflight experience for economy class. There wasn’t any, or at least non that I was aware of.

I liked the friendliness of the employees at the airport

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

Crew were quite friendly. Food was very poor considering the price of the ticket and the flight time. Could not charge my phone due to USB charger not working..

The food wasn’t good. Need better food. There wasn’t any entertainment.

STEWARDESSES WERE AWESOME! The food could be a bit better. Rice was SOGGY with gravy and the chicken was RUBBERY.

I was treated well in first class. I have no complaints. I will definitely fly with my favourite airline again this year.

There was no music on the flights unless you came with your headset.

Their bar selection could be greatly improved; they only had one spirit option
