All major airlines are offering deals in Q1 2017 from their NYC hubs to Vegas, San Francisco, and Los Angeles. From Google Flights you can play with dates and times – these fares are appearing for many dates through mid March.
These are great deals for transcon flight – it doesn’t get much lower than this, especially on all the airlines with tons of availability.
Remember that on direct flights, you generally can’t get a complimentary upgrade to LAX and SFO – although there are ways around this.
