I Have pre booked 2 exit row seats on Virgin for our trip to Vegas from Gatwick. I have been informed that because they need to make sure you are fit and can open the door in an emergency you cannot check in on line but instead use a dedicated check in at the airport to collect your boarding pass and see exactly where your seat is allocated. Is this correct and has anyone done this? Apparently even if I look on line the seat plan will not be available for me to view as my seat is already assigned ( in as much as its an exit row - won't know which one until we check in). Just like to hear from anyone who has done this so I get it clear exactly what I have to do. Thanks.
