United, Southwest, and Delta have round-trip flights from Denver (DEN) to Las Vegas, Los Angeles, Chicago, Miami, Philadelphia, Boston, Santa Barbara, Milwaukee, or Minneapolis (LAS, LAX, ORD, MIA, PHL, BOS, SBA, MKE, MSP) for $97-$151, NONSTOP. Flights August to December. Weekends available. Origin/Destination reversible. No Christmas dates available.
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”.
United’s “Basic Economy” fares do not allow for a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding.
