Yes the three old ladies (G-DEBK/L/M) re-registered as G-DEFK etc carried on in Swissair colours until the bitter end. They then went to Aberdeen for the oil contract but are now being retired due to their VERY high cycles.
G-DEBE also went to Flightline (and was never re-registered) but is now on dry lease to Cityjet and is operating in AF colours.
Flightline have just gained another old Deb one - I think from BMI Regional and have registered it as G-FLTB. Dont know which one.
Still lots of ex-debs crews at Flightline, and after the last 6 months there I hope this is more work for them!!!!
