I got a pretty sweet 1-way business class itinerary... PRG-FRA-LHR-LAX. The last leg is in Virgin Atlantic Upper Class. Sweet! How do i select seats for this leg? I don't see a Virgin record locator anywhere (for me to reference if I call Virgin directly), and if I try to select a seat, it shows me an economy seat map with no available seats. I've confirmed that this leg is in business, as it says so in the receipt / record locator. Thanks!
