We flew down from Dabolim to Cochin a couple of years ago, if memory serves me it was about a three hour flight.We came back, overnight by train getting in to Goa about midday. We travelled 2nd class AC sleeper, that was absolutley fine. The beds are three tier on one side of the passage, and two on the other side, so it's best to try and book that side, great fun, they fold up during the day into seats so there is eight in each sleeping section. You get loads of food during the journey as part of the ticket, and vendors move up and down the train all the time with drinks and snacks, would recommend the journey to anyone ALAN
