I understand the concept of seniority when it comes to bidding trips, etc. However, I do have one question:
Is seniority based on time at the company, or is it based on time at the specific base?
For example, who would have seniority in this scenario: Person A has been a captain for 4 years and has been at the same base for all 4 years. Person B has been a captain for 8 years but transferred bases and has been at the same base as Person A for only 1 year? Who would have seniority? Person A because they have been at the base longer? Or person B because they have been at the company longer?
Seniority is based strictly on your time with he company. In your scenario, person B would have more seniority.
Seniority is EVERYTHING and as Chris said it’s solely based on your time with the company. To give you an extreme example we recently had a VERY senior pilot who for quality of life reasons remained an FO on our 717 (our most jr aircraft) for many years. He recently decided it was time and made the move to the A330 Capt, our most senior airplane. He’s now at the top of the list as a Capt above guys who’ve been flying that plane and been Capts for decades.
