HI everybody! OP here! Sorry that I wasn't detailed enough! I decided to go ahead and do it. Thanks for the opinions! :-) ...

In my case, the flights I originally booked, which were extremely empty, were cancelled and appear to have been consolidated with other flights in the schedule change they did the other day (early October flights). Some of the E+ seats were actually going for MORE than the first/business seats were! I do have the United card, so one bag was already covered, but I am a terrible packer, so not having to stress about a second bag, especially if I over buy while there is a good thing for me! Add in a couple of included drinks, and a slightly smaller line in immigration, and I'm happy with my decision!

Thanks again!
