What is the EasyJet story ?
I suspect this means the FlyBe story (If there’s an EasyJet story I apologise!).
In August 2019 the Cambridge family travelled from Norfolk to Aberdeen on a FlyBe flight. They sat in the very front rows of the plane, getting on last, and exiting first (i.e. the usual security protocol for VIPs on scheduled flights). As they walked across the tarmac at Aberdeen airport they were filmed by people still on the plane.
It then transpired that FlyBe had realised a few days in advance of the flight (likely when the request was made about seat allocation and boarding) that the Cambridge family and their security detail would be travelling on this scheduled flight. The company made the decision to swap the plane that normally makes this run (an Eastern Airlines-branded plane, which partnered with Flybe) for a Flybe-branded aircraft. This was interpreted as an attempt to maximise press coverage for Flybe. Eastern Airways confirmed that this swap had happened. It involved the Eastern Airways plane that had flown down from Aberdeen earlier in the day being flown away empty to get it out of the way, while and empty FlyBe aircraft was flown to Norwich to pick up the passengers that had booked onto the flight.
The airline also stated that William and Kate were completely unaware of the switch and had not asked for special treatment, aside from their security request to board last/leave first
Anyway, as this happened mere days after Meghan and Harry had been criticised by the press for taking a lot of private jet flights in a short period of time, Cambridge hate-sites posited that this was all a plot by William and Kate to show up their brother and sister in law (and that it made a mockery of their eco-credentials as it involved empty planes being flown around). That is the line that has been taken by posters on these threads also, despite no actual evidence for this interpretation.
(I note Kate and two of her children travelled up to Aberdeen again on a scheduled flight a couple of weeks ago, and against were photographed walking across the tarmac. I await this being the taken up as latest instalment in the alleged smear campaign….)
