Looks like they made up some new rules for those matching from other frequent flyer programs:
· You need to provide a valid, current annual statement that will show you have sufficient travel on the VAA (or JV) network to maintain the status – Please send in a valid statement of your past years travel with your current preferred airline.
· You need to have a future revenue flight booked with VAA in either Premium Economy or Upper Class - Please provide a valid booking reference for a Virgin Atlantic flight.
