Come on guys, of course it would be an upgrade.
SIA Cargo is run by amateurs. It's a day to day operation without any long term targets or plans.
Roster changes happens daily and if you're less than 24 hours delayed you're considered on time. Only the complete lack of respect for the crew members private life allows rostering like this.
They assign the cheapest maintenance and station handling everywhere and the lack of quality is showing.
SIA Cargo has turned in to a second class airline. It is possible to change direction but I doubt the management is willing to do it.
I do agree that flying freighters is nicer than having a bunch of pax in the back but if you look at the total lifestyle I'd go for the pax fleet anytime.
