I was flying CO on TUS-BWI via IAH last Tuesday and was surprised to get upgraded on both legs as a OnePass Silver Elite. Of course I was thrilled (never mind the flight was an hour late departing IAH due to a missing crew member) but it got me wondering: are there routes where us lowly Silvers are regularly upgraded? I have never had any success on transcons, but IAH-BWI seems like a route with a good shot. Any others? Any info appreciated!
PS I know the golds and platniums here (though way more on FlyerTalk) hate the idea of Silver upgrades, but hey, that's why I spend the hundreds of extra dollars a year to fly CO, so please don't flame for being a lowly Silver and turn this into a "Silvers suck" thread. Thanks, AZStagecoach
