I have flights booked 23-27 December and have just tried booking National Express from Gatwick-London Victoria. I can book the first leg but nothing is coming up for the return journey. Gatwick express is currently out of service and the two other train services are only showing journeys up to 16/12. Does anyone know if that means that there aren't any trains or will they be shown closer to the time? I'm panicking a bit as I don't want to end up having to get a taxi!
