Also 2219, and possible options
I too am bummed about the deletion of NW 219/220 or NW2219/2220 (or more than a decade ago flt 925/926). I've flown the early morning flight out of SEA and noon flight out of HNL almost all of the time for the past three decades.... Effective Spring 2010, it will be down to one flight daily.
Options: It may be possible NW may allow you to fly AS metal (AS 851/852), depending on itineraries.... Call the rez center if this option can be made available....
