I fly on Delta Airlines all the time. and on each trip my boarding passes always have my full first and last names printed on them, but my middle name is partially cut off (middle name is 'Jameson' but only shows up as 'James'). It has never been an issue at the TSA checkpoints when flying domestically here in the U.S. I'm flying to Germany later this year for the first time. Should there be any issue with this when going through the checkpoint in Frankfurt for the flight back to the U.S.?
