Did you forget your carry on?
You can leave your baggage at the front desk.
I think it would definitely take more than thirty minutes to go through customs and baggage claim.
Remember 荷物 and how it means "baggage" or "luggage." Add a hand to it and you have hand baggage or hand luggage.
If you know 荷物 and you know 手, then you should be able to Voltron the two together into one mega reading.
