Flight time. The crew was the rudest, talked down to customers, ignored requests, acted like security guards, used forceful language like must and can't. Everything was on purchase, no entertainment, unless you could use your own phone. Poor customer service.

Flight time. The crew was the rudest, talked down to customers, ignored requests, acted like security guards, used forceful language like must and can't. Everything was on purchase, no entertainment, unless you could use your own phone. Poor customer service.

Checking in, boarding, the food and crew were all excellent. It was my first time traveling on Caribbean Airlines and trust me it’s the only airline I’ll be flying on as of now as long as it’s going my way😁. The service was unbelievably good I don’t regret missing my flight on flair at all cause I wouldn’t have realized how great the service is on Caribbean Airlines

The flight could'nt be better ,the comfort ,the crew and everything was good.i will definitely fly with this sirline again.

I love my entire experience. What I love most, was the friendliness and helpfulness of the staff at check-in and that of the crew on the flight. Their Customer Service was paramount.

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.
