Obviously it's because no one cares for VX
. Their arrival on the scene was tainted by controversy over the citizenship of their intital investors in defiance of U.S. law. Only after the US Dept. of Transportation forced them to readjust their ownership were they deemed legal to continue operating as a majority U.S. owned carrier.
They'll always be the black sheep after that....basically no one will work with them or basically have anything to do with them. VX
doesn't even have interline agreements (standard practice in the industry...allows for honoring each other's tickets or transfering luggage) with any U.S. airline except one....HA
From the VX
website: Virgin America has interline agreements with Virgin Australia, Virgin Atlantic, Air New Zealand, Emirates, Korean Air, Singapore Airlines, Cathay Pacific, South African Airways, El Al, Qantas, China Airlines, Ethiopian Airlines, Hawaiian Airlines and Air Pacific.
