As a side note
On the way back from a Cave diving trip around the Tulum area last
year we transited via Atlanta, flying Delta.
Now we only had a three hour connection time, then out of four bags
three were checked by the TSA (LOTS of odd shaped metal in the Cave rigs)
and.... Drum roll.........
The only bag that missed the connection was the one they DIDN'T check....
Arrived by courier the next day after a side trip via Heathrow :-)
Oh well... Never been able to figure that one!
