So they check all the luggage for a second time in DXB, but do they also check my suitcase? I have never seen this before that customs check all the baggage a second time when you are on transit. Baggage is already screened by customs at the airport where I departed, so why a second check?
Not quite sure how we can make this any clearer...
You do not have to get your checked-in baggage at Dubai. Your checked-in baggage will be transferred automatically to your next flight.
You hand baggage will need to be re-screened. This is the same as most other airports.
