I am flying from LGW to Orlando in May on Virgin Atlantic and am able to pre-assign my seat 60 days before departure (luckily we fly before the new changes kick in to the seat assignment policy. I am also aware that as the pre-assignment is still currently free than my request is not guaranteed).
My question is to people who have pre-assigned seats before (I have but cannot for the life of me remember timings) - do they open this service exactly 60 days beforehand i.e. to the exact hour of your actual flight?
Hope this makes sense.
