We are doing this, but loading the cargo on the seats, under the seats, and in the overheads. Too much work taking the seats out, and we are doing a mix of passenger and cargo flights. I'd love some seatpacks, but they are hard to come by, and expensive.

We have to carry a flight attendant, or extra pilot, as the regs state that the cargo must be monitored "by someone appropriately trained during all stages of flight", so having one of the pilots wander down the back every now and then isn't sufficient.

A dedicated freighter aircraft has a higher level of fire suppression systems which would be absent on a temporary conversion such as this. Cabin crew are trained in fire fighting and tested annually as part of the security and emergency procedures program. They undergo additional training to qualify to operate cargo flights.

The types of dangerous goods that can be carried are more restrictive than a purpose built or certified P2F conversion.
