Kind of funny I stumbled onto this thread, because I was just female dogging about this very subject yesterday. Don't spend a whole lotta time in these parts
I started a Premier Plat challenge back in January, since I was going to be based part time in IAH this year. On 11 CPU eligible flights, I cleared exactly 1 CPU. I even missed out on a 6:30 AM DFW-IAH flight on a SATURDAY morning, for crying out loud. Now I know I don't fly the most expensive fares and some of my flights are elite heavy (IAH-DCA/SEA), but 1/11 is pretty bad. My 1 upgrade was on a SFO-DFW CR7 "dinner" flight
In contrast, I'm 11/12 as an AA EXP this year, missing a Friday afternoon DCA-MIA, and 4/5 as a DL FO last year. Anyways...
