Some of the teething problems seemed a bit off. I would have expected that they would have done a significant amount of training on the ground (or at least got the crews familiar with the menu.) I have in the past gone to restaurants soft launches. They tend to offer 1/2 price food on the understand that they are familiarizing themselves with the service. I doubt they would invite critics to such an session.
Maybe it isn't easy to test these things on a mock-up aircraft in a warehouse.
I suspect Richard Branson is probably glad he didn't have the vloggers back in the day he did his first virgin Atlantic flight. I am not sure if the CEO was actually on board or just at the airport. Watching the reviews, they may still be sorting these teething problems for a few flights. will the public for this on the job trianing, or just use Delta from Edinburgh? We will see.
In the past, airlines have got volunteers/staff to act as passengers on a ‘simulated’ flight. ie, the aircraft sits on the ground for 12 hours, but a full meal service & IFE etc is provided to check everything works smoothly. No need for a simulator in a warehouse.
BA certainly did this when their first 380 arrived.
As for Global, no one seems to be know if they are HiFly cabin crew or their own.
The whole operation is very bizarre. They only own the aircraft and don’t have an AOC (hence using HiFly). Bookings are done through another company and use their ATOL protection, as again Global don’t have their own.
There is no ‘plan’ beyond these 2 random charter flights. You surely would know your business plan before even thinking about buying an aircraft.
Can suggest reading the thread on PPRUNE forums.
