Domicile Seniority

I have seen in a couple of threads that various bases or domiciles tend to be a “more senior” or “less senior” base. After doing a GOOGLE search, I was unsuccessful in finding a list of some sort. Is there a list of domiciles ordered based off seniority, or is this just a piece of street knowledge you gain as you “fly” through your career?

-My desire is to be based out of BOS. Is BOS a more senior domicile?

-Is this an accurate website showing the various pilot domiciles?

-Is it common for an airline to remove operation from a particular domicile?

Thanks for all the help on these forums! Loving all the info.

As far as I know, the ONLY airlines with bases in Boston are Cape Air and JetBlue.

Was unable to open your link. Good luck!

On the Pilot Domiciles it says American is also one of the airlines there.
Thanks for the feedback Jordan, I edited the link, hopefully it works now.
Thanks! I’m in the planning phase right now and working up to my PPL checkride.

You’d be correct! Looks like it is as well.


BOS is currently a junior base for JetBlue.


That map seems pretty accurate.

You will not be able to find the information that you are looking for, it simply isn’t out there on the web.

Seniority at bases is highly complex and is not necessarily linear. For example, EWR is a very senior 777 base for United, but a junior base for the 737. This is just something that you will have to learn in time.

Speaking in very broad terms though, I think you will find that Boston is more senior than average as there simply are not a lot of airlines that have large bases there.

While not common, airlines do sometimes close bases and transfer operations to other airports.
