I hope BWI doesn’t become a base. The more bases you have the more you dilute the other existing bases leading to less flexibility (read: open time for swapping, look at ACY). Especially when placed in locations like BWI where no one wants to live and a new base doesn’t help anyone.
Now, another west coast base where people might actually want to live could improve qol for many even with dilution of the other bases.
A hand full of big bases is best for qol as opposed to a bunch of small ones. How much swapping to you think Allegiant pilots do? Basically zero. Like I tell my kids, you get what you get and you don’t get upset. Who wants that?
