I have an upcoming flight in NH C. Is it definitely worth the headache and time consumed (dealing with clueless UA agents) and 50k UA miles to upgrade to F on NH1, which is a 14 hour flight?
I thought NH C was vastly superior to any other C class that I have experienced for the soft product. Much better than SQ C, for example. However, the seats are not good for sleeping. Because it's a daytime flight then it's not high priority, but I would not have minded a 3-4 hour nap towards the end of the flight. By the time you land it's around 3 am EST so you are pretty groggy if you haven't been sleeping and have been guzzling champagne.
p.s. I was one of two people on LH F on IAD-MUC. The other guy dressed in shorts and flip-flops had a beer and then crashed without having any meal, so I had personal service for the entire dinner service. Too bad it was such a short flight; we had a good tail wind too.
