When you figure FRA out clue me in. I've transited through, or ended there, there a dozen times and the place still confuses me.
Just last week I transited through on LH flying LHR-FRA-IAD (always take the long way home if possible) and couldn't figure out why no one wanted to see my passport? Not at LHR. Not at FRA.
Yes someone help me with FRA too. Every time I fly from Europe to FRA and then try to connect back to the USA. I see signs saying not to leave the area if you are flying back to the United State, but I swaer after the 1 mile walk following the signs I end up at the same place I could have been if I just walked out of security.
