Aaah - that makes sense...
Presumeably, however, if you transferred over to Long Haul from a Ground Position (for example) via a Blue Notice, you would NOT have your years of service transferred across for the purposes of seniority, etc?
Career Progression (if memory serves), along with Divisional Transfers (to or from Short and Long Haul) are the only methods where this occurs, as I recall.
Correct me at will people - just idle curiosity on my part!
