Now On the flights we had attendants on they were all young, cheerful women who were extremely helpful.
As far as catering it all depends, most of the time it was excellent, we ordered what we wanted and it showed up. I usually had stuff from Panera Bread. I usually was working on the flights so I didn't have time to kick back, but most of them have entertainment systems, the 727 had a full state room as did the Falcon 900. The most uncomfortable planes are the Lear, and the Hawker.
The hawker has a fixed inner armrest (and almost all hawkers do) and it's uncomfortable.
The level of convenience is amazing, you show up and the pilots ask if you are ready to leave, not them telling you it's time to go. Depending on the FBO you can drive your car onto the tarmac and they will valet it back to the parking area. Your rental car is right inside, and all you do is sign and drive.
If you have work to do it's the best and only way to travel. You arrive fresh, crisp and ready to work, and can be productive in the sky. All the planes I traveld on had full telephones too. Having a full lav is nice but on short hops it's better to use the FBO's. As far as announcements on the fractional and charter flights the co pilot does a safety briefing, on the company planes it basically comes down to. The pilot yelling back "And they're off" as we begin our take off roll. My only complaint is the Cessna's have this seat belt chime which is so loud it doesn't sound like a chime at first, it sounds like a loud alarm buzzer. It's an odd sound but all you cessna flyers will know what I mean. But if you can afford $1000-5000 an hour it's the best way to fly. If you have to work and you absolutely postively have be there now it's the only way. Any questions please ask.
