Looking at this winter i see 757s consistently on BOS-LAX/SFO again. There's lie flats offered everyday, but not every flight. Huge upgrade. I am guessing they have more slack with JFK going away. Will BOS-LAX/SFO go back to a "premium" transcontinental route again? Lounge access, real pillows/ blankets and noise cancelling headphones would be such a nice amenity upgrade.
