Could definitely hear the brain strain in the DAL-N guy's voices today trying to say Delta. Also more than the usual calls on guard to -N flight numbers. It's hard to tune up the ears for something new like that.

Got a text from one of my buddies that works at pinnacle in DTW saying "I think I've heard Northwe....er.....Delta xxxx about 100 times so far today."



As far as "Northwest colors," since there is only one callsign now, that will not be utilized.



FWIW, the last airplane to use the "Northwest" callsign was NWA802 from HNL-ATL that landed this morning. I'll really miss hearing it....
