I read on this site (and I think the Delta post) that someone posted "all international flights have free drinks".

Is this true, or only in first class?
I guess that the Caribbean is not considered international because I have never received free drinks on a CO/US/AA or DL going to the islands.

I will be going to CCS (then to PMV) in Nov. This is my first international flight ever to another continent (other than the carib islands or Hawaii).

What type of aircraft is the CO from EWR>CCS?
Are there free drinks on CO and on DL coach?

Any thoughts or suggestions?
