Little space for luggage and the flight was delayed by an hour.

The flight was delayed over a hour and that was over 15 hours in advance not good

At check in I had to pay for my seat that I already paid for on purchasing my ticket. The flight was over an hour late and the plane smelt gross.

just a child who screamed and threw tantrums the entire flight

Excellent experience this was my first time booking with Kayak.

Flight ended up being longer than anticipated because we had to reroute to the Bahamas. So a hour and half flight turned into 5 hours. 0/10.

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.
