Had a shocker when trying to use Airmiles. Being pretty bought in to the Virgin brand for a while Virgin Holidays for the first time has made me think it has to be BA from now on. Have 100k+ Virgin Atlantic miles to use, built up through flying and through Amex spending. When booking a week away to Antigua we let holidays know the intention was to upgrade our outbound flights using airmiles (we paid for return upgrade as it was 'such a good deal') however.... they sold us a ticket that was not eligible for reward upgrades and, we found out at the airport, was also not eligible for a change in class of ticket even if we wanted to pay for it. Response has so far been that Virgin Holidays is a separate company from Virgin Atlantic and virgin Holidays buy tickets from VA on their flights. VA saying that as I booked the holiday with VH then they can't do anything...
