Shamrogue
Will BA/VS etc put on extra a/c?
Tricky at best - there aren't many if any spare aircraft, there few spare crews (and many out of position, holed up on the eastern seaboard), and no/few spare slots into the likes of LHR. Once the flights start up again they'll obviously fill the flights flights they do operate, and possibly move passengers onto any flights/other carriers that do have spare seats, which might perhaps mean asking people to travel to their intended destinations via alternative routes.
