InterCaribbean seems to always be late. I do not recommend it if you have connecting flights with other airlines. The rates are the same as other regional carriers, but their aircraft are not very comfortable and are often quite hot.

InterCaribbean seems to always be late. I do not recommend it if you have connecting flights with other airlines. The rates are the same as other regional carriers, but their aircraft are not very comfortable and are often quite hot.

Flew St Vincent to Barbados on an ATR-40 (?), seating about 60 passengers. Pretty tight in there. Flt. attendant was very friendly. Short flight - up & down in 40 minutes.

No food, no entertainment - half-hour flight (up & down) Smallest plane I’ve ever been on - maybe 60 passenger capacity?

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
