What is a group charter flight? It sounds like a euphemism for passenger plane.

Scheduled services and Charter services operate under entirely different regulations (in the US, anyway). Part 135 carriers don't have to force all the nonsense on their passengers that Part 121 carriers do.

I prefer part 91 but there's some serious overhead there. Also, intercontinental travel is kinda hard.
