I'm NW plat. My EUA eligible flights in 2005:
CO EWR-IAH (1/1 + companion)
CO IAH-EWR (0/1)
NW DTW-EWR (1/1)
CO DCA-IAH (1/1)
CO IAH-MSY (1/1)
CO MSY-EWR (1/1)
CO LGA-CLE (1/1)
CO CLE-PBI (1/1)
CO PBI-EWR (0/1)
NW LGA-MSP (1/3 + companion on the one)
NW MSP-TPA (1/1 + companion)
NW TPA-MEM (1/1 + companion)
NW MEM-EWR (1/1 + companion)
NW MSP-MLI (1/1 + companion)
NW MSP-LGA (1/2)
NW MSP-DEN (1/1 + companion)
NW DEN-DTW (1/1 + companion)
NW DTW-LGA (1/1 + companion)
That's an overall record of 16/21 (76%)
On CO metal only: 7/9 (78%)
On NW metal only: 9/12 (75%), although note that on at least one of the LGA-MSP misses I had a non-elite companion on the same record (didn't split to try to get the NW 5-day plat companion EUA)
Overall pretty good, although the numbers drop dramatically if I figure in all my international, RJ, and DL travel.
