I suspect that codeshares could play a vital role in the viability of SIA's proposed transatlantic MAN-IAH sectors. An arrangement with Star Alliance partner United Airlines would be ideal ... but would United be interested? United / United Express have a major hub operation out of IAH; fantastic connecting opportunities. Meanwhile, Singapore Airlines already codeshares with Virgin Atlantic on MAN-SIN ... another possible partner, but again would Virgin / Delta have any interest in helping SIA establish a competing route to the Southern States?
I'll keep my fingers crossed for a *A codeshare agreement with United. I really don't know how realistic that is though. Can anybody confirm what (if any) codeshares SIA offer on the existing Moscow DME-IAH service?
