The only fares are J or Y type fares , full fares, i booked it to Havana and paid about 1500 all taxes included, it worked out to 750 each person. C class is not allowed, only full fares. I had to go to the airport to have the tkt issued and hand in the coupon. In the process the agent while working on my ticket and talking chatting with her co-workers while a line was forming, ripped off one extra flight coupon from the tkt. Issue was resolved on day of departure.
