Are you basing your percentage on projected numbers or current numbers?
DCA is shrinking if junior pilots leave you will fall in percentage.
EWR is not growing it's just a new hire place holder. You need to base the percentage off of the CA number which is 88.
Hotels in EWR are not that bad $90-100 out the door but remember you will. See to cover LGA. I haven't looked to see how much flying is in LGA but I'm betting it's more than what is in BWI.
