Contact Approach,
Why would you be qualified to be an airline Ops professional, or go through the management training that Jet2 are offering on the basis of holding a FATPL?
You may hold the very basic legal requirement to seek employment as a First Officer, but most FATPL holders wouldn't know how to work a shift in Ops or another airline department.
I see this as a good opportunity to get a good reputation early on in a career and then be paid to fly an aeroplane - all this in an economy and business that has tanked.
