So I am on LAX-BOS Sunday at 4pm (UA164) and it looks like F has about 8 open seats, however there are just 3 of us in E+ (and maybe 50 in E-) on the 752. Does this mean if I do not upgrade I stand a great chance of having a whole row in Y to myself?

If the answer above is Yes, is it just worth it to not burn 6 e500s for the east bound upgrade? (I am not 1K yet and have no cr1s or any other upgrade instruments). I have plenty of UA drink tickets so I can get enough sleep "medicine" in Y to get a little sleep if I can layout across the seats. Am I making good assumptions here?

Thanks for the help.
