I think tommyinyork may have been refering to what happens if a plane is fully converted to freighter configuration, like the B747F or B757F

Hi Guys

Don’t forget its not Channel Express (Bournemouth) anymore. The Dart Group plc Aviation division now trades as Jet2.com Ltd based at Leeds/Bradford Airport.

So Jet2.com now do in fact operate freight aircraft as follows. Boeing 737-300SW, G-CELW is pure freight ONLY aircraft. Where as the others G-CELA, G-CELP, G-CELR, G-CELY, G-CELZ are QC variants and so is the newest arrival to the fleet G-CELO. These Quick Change Aircraft can be changed from a Freight config into a 147 seater Passenger config in about 45 mins.
