Free ticket seat allocation
Could anyone tell me how the number of seats on a particular flight are allocated for people who want to book using their frequent flyer miles.
Are there a certain number set aside, and when they have been taken that's it, or if there are spare seats near to the flight date, are more made available.
I'm trying to book a ticket on Virgin, but I can't get a seat for the return leg, and I was wondering if it's worth me keep trying, to see if any more seats become available nearer the required date.
Thanks for any info.
