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

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.

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.
