Just woke up in Vegas (yes I know light weight) and noticed Tinkerbell is on her way here, am I right in thinking she's a LHR config. I checked in online an confirmed 6a and k yesterday but am thinking that won't be accurate this afternoon?
Am sure Tinkerbell is still in LHR config (& had been planned to have left the fleet by now). In theory, VS will map over all existing seat requests, so if you had 6A/K on the LGW config, you're now in 12A/K.
Interestingly, Virgin IT have been halfway on the ball - the seat maps for the LHR config 747's have been removed from their website. This must be a record for them!
If your return flight home is fairly full, there will be some very happy PE passengers who get a nicer seat, but still with PE service.
