Hallo Artemis!
Gut gegooglet ist halb gefunden; das sagt der Flughafen dazu:
‚Shocon‘ stands for ‘short connection’, transfer baggage
with a very short connection time. This transfer baggage is
channelled through the baggage-handling system to the
connecting flight as quickly as possible. In exceptional
cases, transfer baggage with an extremely short connection
time will be taken directly to the connecting aircraft. This
procedure is referred to as ‘tail-to-tail’ because of the
position of the baggage holds: in the rear of the aircraft.
Gruß,
Stefan
