I really hope that VS/CO/other do launch services from DSA. There is far too much Doncaster-bashing on this site. Fact is Manchester is not the hub of all life North of London and I suspect that many passengers using the services from MAN to the USA actually live in Yorkshire. Hence DSA would be more convenient for most of them. Regards connecting traffic; I doubt many passengers connect at MAN onto the VS service to Orlando hence imo the lack of connecting flights at DSA is not an issue. My money would go on a Continental service to Newark allowing many connections at that end; I'm sure there's demand and DSA has the longest runway in Yorkshire.
