i can definitely say my percentage is improving as a 1K in NYC (i usually fly from EWR but sometimes throw in LGA and JFK). all flights have been domestic/mexico this year - 62 segments on UA/UAX.

TOTAL UAX FLIGHTS - 24 segments
UAX single cabin - 18 segments

UAX dual cabin upgraded - 5 segments
UAX dual cabin not upgraded - 1 segment
(upgrade percentage on UAX with F is 83%)


TOTAL UA MAINLINE FLIGHTS - 38 segments
upgraded - 29 segments
not upgraded - 9 segments
(upgrade percentage on UA mainline is 76%)

of those 9 segments not upgraded, 7 were flights before March 15, 2013. and of those 9 segments not upgraded, 5 were SDC flights at the last minute.

so my upgrade percentage prior to March 15th was 59% and since March 15th has been 90% on UA mainline flights. things are looking up for this 1K.
