I don´t think I´ve ever been so ready to bust a blood vessel as when I was transiting through Miami on Monday. Held up by a late flight from London (1 hour)and by the new US security procedures (1 1/2 hours), I had less than an hour to check in and do security for my next flight. After a series of extraordinarily unhelpful people told me different things and waved me vaguely in a number of directions, I finally had almost to cry to get someone to help me when the machine told me I was too late to check in. And the tears welling up were real. All I can say is God bless that lovely man and all his family and all his descendants. It wasn´t over, however, because there were about 400 people in front of me in the queue for security. If it hadn´t been for another lovely lady (God bless her etc) who sent me to the Special circumstances queue where there were only 6 people in front of me, I might still have been there into the night. Never ever go to Miami airport. Unless you are very lucky, no one will help you and there´s probably better signage to your bedroom than there is there.
