I still think the first in last out seniority option is the best while not perfect promotes and encourages stability. A new joiner to a company like BA or Virgin atlantic where pilots have to wait for years to get to the lhs will beless likely to leave after a long time. I have friends who work for both long term and not planning on leaving. This is compared to ryanair and easy where pilots jump in and out on a regular basis or as seen as companies to build experince.
And guys sory for asking what does Lico stand for?
