Oh I recognize that I'm ridiculously spoiled when it comes to plane times. I've been in Denver for a while, and it's generally 2-3 hours to most places; a four hour flight seems long!
And we've been looking at flights to places around Europe from where we are in the Netherlands and again, it seems like a lot of places are in that same 2-3 hour timeframe, so spoiled again. The flight over from the US is generally 9-ish hours, and I'm getting used to that. I trick my mind into thinking it's night, so that's my sleep time, and when we arrive, that's my day. (At least, I don't mind the flight so much when I can sleep, but that always depends on my neighbors).
I haven't done a flights of longer than 10 hours I don't think, so an 18+ hour flight seems a little intimidating. Any tips for the longer flights?
