Jethro's reporting that AirTanker A330 G-VYGL has now had it’s lease extended to Nov 2025, and will be repainted into Jet2 Holidays livery this month!
I'd concur with other posts, not being done this month. My best guess if its hanging around for a few more years would be to paint it in the quieter Winter months, when they perhaps don't need all the capacity it offers.
That being said, GL is almost 5 years old, could it be coming up to a large maintenance check? Might have time to squeeze in a paint session then (whenever that is, as has been reported before, it's flying flat out until at least end of August)
