Who knows where this could go? Not me for sure.
However, there is a big push from balpa (BA) to ensure pilots operating this work are on the BA list.
Due to the nature of the work patterns, and the salaries currently muted, it may not prove particularly popular with many 'nigels', even if it is made available!
Five (two pilot) transatlantics a month, may not sound arduous to people for whom it is new, however, over a period of time, it will take it's toll perhaps??
900 hours a year won't appeal to everyone. I can easily imagine this would turn into a 'stepping stone' airline, where people take the experience, and run.
Enjoy.
