UPGRADE WANTED

problem going out; it’s a daytime flight, with plenty of entertainment. Coming back overnight is a different matter; I would simply ask at the airport if upgrades are being sold, and decide if the price is reasonable; last time I flew on Virgin Atlantic (from Shanghai to London), upgrades to Premium Economy were being sold for $200 (£165).
Upgrading only inbound also means you avoid paying double Air Passenger Duty, which applies in all but basic economy from the UK.
