American Airlines and Southwest have round-trip flights from Dallas (DFW) to Philadelphia, Las Vegas, San Diego, Orlando, Pittsburgh, or San Jose, California (PHL) for $139-$144, NONSTOP. Flights August to November. Most departures are on Tuesdays, Wednesdays, or Saturdays. Extended weekends available. Origin/Destination reversible. No Thanksgiving dates.

Note: Southwest is matching on some of these routes but to get the discount requires jumping through a few annoying hoops. First, you can only see the fare in their slow and buggy Southwest (mobile phone) App. Second, you have to use code “BDAY”. 

A Carry-on bag and also a personal item is allowed for free on American. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.
