For Airbus and 747 crews,seniority based type transfer is the number one issue, above all of the other multiple issues that we face, in order to see some light at the end of a long,dark tunnel.
For 777 crews, it is at the bottom of the list.
I disagree. Rostering improvements would mitigate the majority of this issue and positively impact all fleets. Going after seniority type transefers as a top priority is short-sighted and foolish.
