Most expensive bases tend to be senior.....with a few exceptions of course.

Silver Saab - IAD
Silver Beech - CLE (but nobody is being hired into the Beech anymore)

There are currently junior bases at Eagle/envoy but they are always in a state of flux. Look at bid awards and such, it seems most FOs get which ever base they want within a year of starting training - the delay mainly caused by waiting for vacancy bids and then transfer dates.

The problem comes when the CRJ is the equipment awarded in class because then you are stuck with ORD or New York. However, with the DFW base opening, that is an option. And a person who is still in training was awarded DFW CRJ FO on this latest vacancy bid.

When LAX existed, it was the the most senior base by a considerable margin.

Endeavor: JFK is junior DTW is senior. That trend has every indication of becoming more lopsided. If you are hired here expect to spend a LOOOONNNGG time based in JFK or LGA.

What are the junior bases for SKW (for both CRJ and Bro)?

At Horizon, you can currently hold any base you want as a new hire... as long as it isn't Anchorage.

I meant most expensive bases tend to be JUNIOR.

I'm pretty sure it's been addressed but...

CRJ: MSP/ORD/COS
Brasillia: FAT/SFO/LAX
