I lost my passport at Lisbon Airport. Here's what I learned:

I was about to board the plane from Lisbon to Madeira when I noticed I couldn't find my passport anywhere. How? I'm not the type of person who loses anything. Keys, wallet, phone and passport are always in my pockets and I check them frequently. But this time, my passport really seemed to have disappeared. I didn't have much time left, but the only option I could think of is to start walking back to the security check. Maybe it somehow fell on the way here. I went all the way back to the security check and asked the staff if they had seen a passport. They told me to sit down and wait. The plane was already boarding so my time was running out. Just when I thought I should just go without it and figure it out later, the officer came back with good news. Here's what had happened:

Here's how it happens: You come in a hurry, thinking about a hundred different things at once. Are my liquids correctly packed? Do I have to take out my laptop? Is it ok to keep my watch on? Then the staff signs you to take a tray and put everything in it. The line behind is long so getting it done quickly is just good manners. You leave all your valuables on to the conveyor belt and watch them disappear inside the x-ray machine.

That's what happened to me, had happened countless of times and I thought everything was okay. However, somehow inside the machine my passport had fallen from the tray and slipped between the conveyor belts. I have no idea how it happened or if anything else had fallen, but apparently it happens a lot.
It's easy to miss, because the same urgency and hectic environment continues on the other side, when you have to take everything from the tray and get going. You stuff everything back in to your pockets and put the tray back so others can do the same.
I was lucky to get my passport back when the odds were clearly against it. It was the not my fault, but it could have ruined the trip before it started.

I analysed what had happened and studied why people often lose things. Everything clicked into place and the solution was simple: a dedicated bag for everything important. Because pockets can be risky, and a backpack is too far to reach. It needs to be a small, lockable pouch within your sight at all times. That's a why I designed the Travel Sling Bag the way it is: Perfectly sized concealable extra pocket with security features.

It's so simple but needs the correct bag to pull it off. Backpack or carry-on luggage in for larger items, and a Travel Sling Bag for those small items you can't lose. Make it a routine and add a tracking device for extra safety.

I have a two bag strategy. Only carry on so I save on luggage fees and lower the risk of losing anything. A Travel Backpack in the back, a Sling Bag in the front. Everything I might need on the plane or at the airport is in the sling bag, so I don't need to start digging the carefully packed backpack at any point. I've done this many times and it's as smooth as it can get.

I might be biased, but this is the way to travel in 2026. You already know why the Sling beats backpacks and pockets, so here's how it beats other sling bags:
It all comes down to size, access and security. You want a bag that is out of your way but fast and easy to access at the same time. Most slings are big and bulky, and the whole idea of staying agile and having easy access goes out the window.

In addition, the locking zippers and security features make keeping valuables inside safer than other bags. You really want to be sure the zips don't open by accident.
