Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

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

Caribbean airline sucks… they have a promotion to bring 60lbs in your suitcase.. meanwhile when you reached your destination (JFK)… your suitcase didn’t show up. They had too much weight so the suitcase was left in Guyana… like WTF????? Stupid promotion.. just like the uneducated people working with the airline. The representative said there is nothing she can do about it… will not use them again.

Boarding the flight was smooth and the flight was not full so i had an extra seat essentially

There was no flight. They canceled the flight with no knowledge to me, and I still haven’t received a refund

Overall, it was good. There was no food or entertainment, which is why I put poor (it wasn't an issue though).

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.

This flight was great. The plane took off and arrived at the destination an hour early. The crew was pleasant. The food and entertainment options are minimal but adequate for a 1-hour flight. They passed out water and quickly supplied me with a fresh magazine since the previous one had the crossword section filled out.

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.

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

We had several flights and they were all on-time and flawless

For a 4 1/2 hour international flight all we got was 1 small pack of cookies and a drink. You had to watch movies on your own devise.

I’m sure Business Class would be excellent. I feel like I got what I paid for. Overall it was good and well worth it. I would do it again.

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Crew at the gate was very crabby and not at all polite. The plane was very hot the entire flight. And the seat cushion was very worn out.

The staff are very, very professional. It's what flying should feel like.

The flight attendant in business class was excellent! Professional, friendly and attentive.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.
