  1. What is also great about this deal is that most places can get a $15 deal to Chicago or Denver which means you can go transcontinental for $60 round trip if you don’t mind laying over Tues. night in Denver or Chicago.

    From here in Philly I could do Philly to Chicago, then Chicago to LAX the next day and do the same on the way back.
