Delta has BusinessElite lounges at JFK, LAX, and ATL.
Do domestic business class passengers have access to those lounges? For example, someone who buys a business class ticket from JFK to LAX. DL has four flights a day that have business class.
...or are these flights simply operated as domestic first class, but with int'l business class seats? (i.e. domestic first class food, IFE, crew, etc....)
