Oh well, all part of happy holidays, I suppose.
I recall flying to the USA with 2 mates, think it was 1995, we were interrogated and searched by USA folk at Gatwick, we laughed it off as all part of the adventure. Another time, USA again, got air side to board, 2 hour wait, got on the plane, sat on it for 3 hours, total of 5 hours, all part of happy holidays....????
I am sure we all have tales to tell...????
