LAX because that is where the people are
LGA (only) because if NK bows out likely we would be first in line for the terminal they set up.

That's what my money is on.

CLE Started great... last few times I was in there It was falling apart and poorly run (par for F9)

I 100% believe it's a top MX base that area of the country has exceptional mechanics, Always has. A strong MX base is enough reason to hold onto CLE.

Again that's what my money is on
