Yes, although the only missed upgrades to/from EWR in the last two years were to/from IAH. I've found that route to be highly unpredictable. I've got instances of the same flight, same day of the week, same time of day, same equipment, where I have upgrades that came 5 days out, the day before, battlefield, and no upgrade at all -- and there is really no pattern to it. The only reason I really don't complain about missed IAH-EWR upgrades is that they are pretty much all on 767s, and I've almost always had a bulkhead seat in the mini-Y cabin right behind BF.

Most of my EWR connections are on COEX, so that makes it difficult for me to provide any real data for upgrades out of EWR, other than to IAH.
