The sooner VS join Skyteam the better. Business travellers will then have far more destinations in order to earn miles and tier points, and thus choose Virgin more.
As I said in a discussion I started last year, Skyteam brings opportunities with Delta, Aeromexico, GOL in Brazil (not Skyteam yet but part Delta owned), Kenya Airways for east, central and southern africa as well as Indian ocean, MEA & Saudia for Middle East/Gulf markets, and a bucket of Chinese carriers. As well as Europe options!
Also they should have invested in the business product similar to DL/LX, AY etc, not the herringbone facing away from the window etc.
Being aprt of skyteam will help both Virgin long haul and Little Red.
