Good Result nidge,
That's useful info as I am in a similar situation re likely treatment and sod's law make it makes it probable that it will clash with a long haul in mid-September.
And of course, the tickets are not flexible. Obviously treatment will take precedence but I'm reluctant to cancel the trip, even though I'm insured. I may have to negotiate a postponement on the flights- fortunately most of the hotels we have booked are cancellable.
Our flights are not with Virgin but with Swiss - so fingers crossed !
Thanks,
Dave
