I think every airline has instances of Crew scheduling either knowingly or unknowingly violating the proper assignment methodology of reserves. That’s also why it’s inportant for anyone on reserve to know who on the list fits for a given trip and if multiple people fit, what order they would be assigned now based on seniority. If one is assigned out of order it’s up to them to politely call scheduling out on it. I have and the mistake was acknowledged and the trip removed from my schedule.

Flica reserve availability isn’t always the easiest to track but if you are uncertain at all after being notified of an assignment, a call back to scheduling and a “hey, can we talk about the assignment methodology of this trip. I’m not sure that I was the next in line. I looks like such and such proabably should’ve gotten the trip”. This tone is non confrontational an allows them to take a fresh look and offer either a valid explanation on why you got the trip or to validate your concerns and remove the assignment.

Matching days and RAP first then if multiple pilots match least seniority gets assigned first as credit no longer has any impact on the assignment with the exception that if the assignment takes a pilot over guarantee scheduling has the option to skip them and go to the next senior pilot.
