Anyone else but me ever get burned out from taking the same flight over and over? I took UA 945 FRA-ORD so many times that now I will take almost any other route to get to the states. It's actually a great flight for my schedule, getting into ORD normally on time and early in the day, upgrading is normally easy, etc. However, mentally I just got tired of it after so many years. Sometimes I'll even combine different airlines just to make it interesting, for example, LH to DFW and AA onward. Only thing I won't do is go through PHL again. Made that mistake experimenting last year on US and got hit with a mass of humanity after exiting customs and immigration. Wow, what a claustrophobic experience.
