Curious Pax, your scenario is a very reasonable one. What does occur to me is what happens if Hainan decide on LGW after all? Would they be prepared to keep to the original MAN deal (without STN), or press MAG to accept the terms they could have had with MAN plus STN? I suppose it could depend on how the 'double' package was structured and whether the same charges applied to both airports or whether the 'discount' favoured STN more strongly.
