12 hours is the norm for me to commute, and that would probably be a good day! As said above no day is great for commuting! I am going on 7 months of commuting from Iowa to California and still figuring it out! Get as many options as you can and have multiple outs through different hubs. I am really getting tired of flying all day, commuting home on a red-eye in the jumpseat as usual, no sleep, getting home to only stay awake all day, and having leave the next day to start another 12 hours of commuting to get back to six straight days of work! "Aaaaaaa living the dream.................?" Good thing I love my job!
