The job is OPERATIONS OPERATIONS OPERATIONS
On a typical trip I am the only cabin crew member on the aircraft. That means I am the one who: places the catering order at least 48 hours out, because changes and requests keep landing inside that window, for a city I may have never landed in and where no catering company exists in any app. I'm writing this from Kyrgyzstan. Bishkek, Osh: there is no supplier list waiting for you, you build one from nothing. On a 14/14 rotation that's around ten catering orders — roughly twenty emails to FBOs and another ten to ops, most of them written on what is technically your rest.
Provisions the aircraft to be self-sufficient across a multi-day rotation, because there is no galley uplift waiting at the next stop. Builds a menu around flight duration, departure time, location, aircraft type and whatever I have been told about the guests, and adapts it when they board with their own food. Coordinates with the FBO, the handler and the crew on timings that move constantly. Manages stock control across sectors and completes post-flight reporting. Absorbs a schedule change at midnight, or a guest request that lands two hours before departure, alone, and makes it work anyway.
Which brings up something nobody mentions in an interview. In commercial, you close the flight and that's it — it's done and it belongs to someone else now. Private doesn't work that way. The trip keeps running day and night, and a good part of the coordination happens in the hours you'd call off. Not at every operator, but at plenty of them, and you should know which one you're joining before you sign. If you want to know exactly what to check, read what to actually look for in a private jet operator's contract.
Duration, location and aircraft type decide that menu before a single ingredient does. You don't have the same galley space on a Challenger that you have on a Global 7500, and you don't propose the same service for a short Paris–Nice hop that you would for a long Nice–Miami crossing. Except when the guest requests otherwise. Then none of it applies, and you make it work anyway.
The passenger sees the result. The job is everything that made the result possible.
