It appears that rail services to Gatwick station will now be affected if the ongoing dispute leads to another strike.

Do enough of BA's LGW staff rely on the railway for short-notice flight cancellations to be likely, were a rail strike to happen? If so, would it constitute an extraordinary circumstance as per EU261?
