I'm trying to travel to Nassau, Bahamas from Colombo, Sri Lanka with 1 connection in London Heathrow.
I am concerned about the "onward" ticket requirement in the DATV transit visa requirement. I think they will not grant it if I am on 2 separate tickets.
I can't seem to get it all on one itinerary. I can see there are flights in February on flightconnections.com but when I searched google flights and ITA, I can't find that route on a single itinerary. I would rather not use a travel agent.
Is this a concern? Is it important to book as a single itinerary?
