I found this thread as I was wondering the same thing but oh well.. Was going across country from Portland Me to SF and met someone on a connection through DTW.. I was tired and slept then we talked when landing and I didn't even realize how fun she was till halfway through second leg when I awoke completely. I'd have no problem asking name and digits but was 5am and on no sleep.... Reminds me of the movie Serendipity (Maybe we meet again as I go through DTW every Month)
