Just looking at booking an alternative outbound flight, now, Our return flight with Vueling, as far as I know, still stands.
As they're two separate flights, they are stand alone flights, not a charter, as such.
That doesn't mean the twats won't cancel that as well, but at this point, lets just get there, and worry about it later.
A day trip is no good to us. We have a grand (none refundable) of two nights accommodation in Madrid.
