They have some unique jobs at the airport that would require months of training to learn! Stacking this mountain of suitcases requires a very special set of skills that few people possess, so this must be one of the job requirements.

They advise us against packing valuable and fragile items in our suitcases since once the luggage leaves our sight, no one can promise that our precious cargo will be handled carefully. With so many suitcases to manage, they can’t afford to handle each separately, and they tend to throw them all in a bundle, as you can see in the picture. From now on, we’ll be packing lightly.
