Is a bag without a lock allowed in a flight?

Okay, so you're wondering if you can take a bag without a lock on a plane? Yeah, totally, you usually can. I mean, most people do, right?

But here's the thing – and I'm speaking from experience here because, you know, I've definitely been that person sprinting through an airport, stressed and a little discombobulated – it's probably a good idea to keep an eye on your stuff. Like, really keep an eye on it.

I always think about my friend Sarah. She was traveling through Europe and left her backpack unattended for, like, two minutes to grab a coffee. Gone. Just gone. Luckily, it was mostly clothes, but still! A real pain.

So yeah, while you can take a bag without a lock, maybe think of it as an invitation for someone with sticky fingers. A simple lock, even a cheap one, is often enough to deter casual theft. And seriously, never, ever leave your bag alone in the airport. It's just not worth the risk, is it? Trust me on that one! I learned it the hard way when I almost lost my laptop charger once! Disaster averted, but still. Lesson learned.
