As said by ClipperNo1, they were using some 727-25QC regs N950UP, N951UP, N95.... on behalf of Vacation Express. Some of their destinations included Louisville, Aruba and Cancun. The service was acceptable (remember that on charter flights the pax get whatever the tour operator pays for). They never hired their own F/A, as they got some from a crew broker, nevertheless they used their own pilots to whom they gave some training about passengers operations.
There are no stupid questions... just stupid people!
