for LA Id look at LAX,LGB,BUR,SNA,ONT, and even SAN
from NY Id look at EWR,JFK,LGA,PHL,BDL (Hartford 2 1/2 hr drtive)
just keep in mind alot of people are planning to do the exact samething and got their tkts awhile ago
some <$300 tkts can be had BUT it means making a stop or 2 and leaving at 6am , Id think in the next week or 2 even those will be history
