NJ David, I'm in the same situation, and while I'm not overly thrilled with the direction CO has been going with regard to diminishing upgrade availablilty--I'm still pretty satisfied with them (although, the first time I'm ever not upgraded--I'm sure I'll post). I too, will always check ITN for seating prospects and look for the larger FC cabins on transcons. But for some of my other flights from EWR (to MDW, ATL, BOS etc) I've done ok with EUA.
PS-Vulcan, I'd be interested to hear how your wife did on her H fare to SFO. Also as a Platinum, I've got an H to LAX next Tues with A9 D5 F0 Y9 H9...And I'm hoping to keep my FC % at 100!!--so I will once again check in at Penn Sta at 6:30am for my 4pm flight and hope for the best.
