As do US carriers on numerous longer routes like jfk-lax or atl-hnl
But those are much longer business and long-haul flights respectively.
In the next month I have six Sydney-Brisbane flights on Qantas (1 hr 20), two Brisbane-Perth (5 hours) and four Brisbane-Melbourne (2 hours) as well as two Johannesburg-Cape Town (2 hours).
Each of the Australian flights - in coach - comes with food, seatback IFE, luggage and soft drinks and liquor. The South African flights have the same except the IFE.
The only US airline which can match that soft product in First Class is Continental!
Returning to the point, I'm a happy Hawaiian Airlines frequent flyer because the fact that First Class is sold but not given away means that all First Class passengers generate significant revenue, and First Class fares are pitched at levels which are consequently extremely good value for money.
