HANG ON JUST A SECOND HERE B412.... You booked a UM on TWO SEPERATE tickets??? What were you thinking? No wonder everything went wrong. That was a very VERY stupid decision on your part and totally exhonerates BMI in my opinion.
However, Maybe I have missed something here!
P.S...Never EVER book a UM with a connection with TWO SEPERATE tickets. You are asking for trouble. Your children are precious, dont cut corners!!!
