Seniority should be eliminated equally everywhere in all airlines worldwide, it's the bane of the pilots existence and causes so much unnecessary grief the positives it may bring are out weighed by the negatives. There may be some professions left that use it (although I can't think of any off-hand) but I believe it's use is outdated and a hindrance to our collective cause whether we like to recognise and accept it or not.
Eliminating it is unlikely happen for the time being unfortunately. Call me a free market radical.
