I've had bad flights with InterCaribbean before (cancellations, no gate agents, etc.), but this one went perfectly smoothly!

Long delay. No AC on the flight from Barbados to St. Lucia.

Did not get to travel, you canceled my flight and left me stranded for the hole day, it's another day and I can't get to my destination. I will not recommend any one to this away, bad service

Delay flight more than 8hours waiting and poor customer service!

Plane was extremely small so mind the size of your carry on

Other than lack of snacks, everything else went very well.

They don’t keep you updated on the flight status very well. It was late but nothing said
