This would be a very interesting move by Vietnam Airlines if they did decide to enter STN, especially given that they already operate at LHR, and had previously tried LGW before consolidating at Heathrow - how likely would a dual STN/LHR operation be? Either way, it would be great to see long haul expand from STN alongside Emirates.
Also, does anyone have any further information or updates regarding the STN transformation programme? IIRC, something was mentioned about MAG supposedly scrapping the arrivals terminal in favour of a new terminal 2?
