Wow, very cool if this does go full time in to the schedule.  I think SFO, LAX and DEN will get bulked up nicely post-merger, with SFO being well overdue in my opinion.

I dont remember anything larger than a 739 on this route but do remember the 753 being used on the cruise ship express to SEA.  Great use of the aircraft that typically sits unused after the afternoon arrival from LAS.
