The airline operated two Boeing 737-3Q8 aircraft manufactured in 1993 on non-scheduled commercial passenger flights on both international and domestic routes.

[1] In 2002, Swiss aviation authorities performed a surprise inspection on SU-ZCF, a Flash Airlines Boeing 737-300.

Poland also banned Flash, while tour operators in Norway ceased contracting.

In early 2004, SU-ZCF crashed while operating Flash's Flight 604 from Sharm el-Sheikh to Paris via Cairo.

The subsequent investigation exposed poor safety measures and pilot disorientation, which led to the demise of Flash.
