Channa,
Everything out of EWR is EXTREMELY competitive when it comes to CO. I do fly LAX, SFO, ORD, BOS, DCA quite a bit. I don't care about BOS and DCA (too short) but it amazes me that I never got an upgrade on either route.
I got denied both ways EWR-FLL-EWR two weeks ago. I wouldn't call that a big business route.
Ok -- I just got upgraded on the SFO-EWR redeye tonight. That makes me 1-4 so far in July. Not really staggering stats. I'm happy to get an exit row most of the time.
