I know that Virgin Atlantic enables seat selection 90 days before departure, and I know that only a percentage of seats can be selected before T-24 hours. If I am booking about a month before departure, can I learn if there are seats to be selected immediately after booking? I can see empty seats on Expert Flyer, but, before I pay for my booking, can I determine if those seats can be selected with the 90-day feature?
As far as I know, the only way to see the actual available seats is via Manage My Booking and that is only available once you have made the booking and paid the money.
An alternative may be to phone to make the booking, and ask the agent to check. I did that when thinking about changing a flight recently and one of the decision points for me was which seats would be available for me to pre-assign.
