Exactly.

And even as a lineholder, you’re defacto reserve. How many trips start off with 1 leg to SEA and the rest of the day off? Bzzzzzzzz ACARs message. FO plz call scheduling upon landing. I go to the hotel, he gets tagged a SEA-DEN-SEA and now the 18 hr layover is down to min rest 10 hrs for him. How many people get their schedule changed going into/out of SEA? A lot. That, and overnighting many in SEA is still far cheaper than opening up a SEA base for the Bus. If we go single fleet, then opening a new Bus base is not a cost effective solution.
