we had a code share with a VERY tight...less than one hour...transfer from EIS to SJU.

Our Cape Air printed tickets did not have TSA-Pre check mark. the line to go through airport security was REALLY LONG at SJU.

I pulled a rabbit out of my hat and went to have our United tickets reprinted at SJU with the TSA-Pre checkmark. 4 people in line in front of us...jumped in front of the numb-n** that was holding up the line, and was able to make our 45 minute connection.
