Years ago great customer service was defined as giving someone the can and some free peanuts. Now it's touch screen "entertainment in-flight systems." Not like any of those things have made the flying experience any better. So I just pick the cheapest flights available. Sure, Wi-Fi is a plus, but the environment in economy isn't exactly ideal for work.
I've primed myself to fall asleep as soon as I get into my seat before takeoff, regardless of time of flight.
