the most important thing if your visa, last year on a charter flight to Goa we were ready for take off and the captain came over the tannoy- has anyone not got a visa and two "wallys" put their hands up and were promptly chucked off the plane ! how was it not spotted at check in ? and on another flight these two guys had won the holiday as a prize in their local pub and they were sent back after they landed in Goa.
