Singapore Airlines Carry On Bag Policy

Let’s be honest—packing for a flight can feel like a game of Tetris where you’re always one block short. You’re stuffing that favorite jacket into your bag, praying the zipper doesn’t give up. But when you’re flying Singapore Airlines, their carry-on policy is like having a friendly flight attendant whispering, “You’ve got this.”

So, what’s the deal? You’re allowed one carry-on bag and one small personal item, like a purse or laptop bag. That’s it—no secret second backpack hidden under your arm. The main bag can’t be bigger than 115 cm in total dimensions (that’s height + width + depth), and it must weigh no more than 7 kg for Economy class.

Think of it like this: if your bag looks like it could house a small cat, it’s probably too big. The airline’s sizers (those metal bins at the gate) are the bouncers of the sky, and they don’t accept excuses. My friend Sarah once tried to bring a “slightly overstuffed” duffel—let’s just say she learned the hard way while repacking in the terminal.

Why should you care about a little weight limit?

Because nobody wants to be that person holding up the boarding line while you dig out your toiletries. Singapore Airlines is famous for their smooth service, and sticking to the policy means you’ll breeze through security like a travel pro. Plus, lighter bags mean more space for your souvenirs from the chili crab stall at Changi Airport.

Now, here’s the golden nugget: Business and First Class passengers get two carry-on items, up to 16 kg total. That’s right—double the allowance. But if you’re like me, flying Economy, the rule is simple: pack light, pack smart. Roll your clothes instead of folding them—it saves space and keeps wrinkles away for that hotel selfie.

What about liquids? You already know the drill: 100 ml per container, all in a one-liter clear bag. But here’s a little story—I once tried to bring a fancy bottle of olive oil from Italy. The security guard just smiled and pointed to the trash bin. Don’t be that person. Stick to travel-sized shampoo and buy your duty-free gifts after you’re through the gate.

The secret weapon: a soft-sided bag

Hard-shell suitcases look sleek, but they’re rigid. A soft-sided duffel or backpack can squeeze into that overhead bin like a cozy pillow. Singapore Airlines allows bags up to 36 cm x 23 cm x 56 cm (roughly the size of a medium carry-on). If you’re unsure, check your bag’s tag—most new luggage has the dimensions printed right there.

Also, don’t forget the personal item rule: smaller than 40 cm x 30 cm x 10 cm. That’s basically a tote bag, not a gym duffel. I once saw a guy try to bring a guitar case as his “personal item.” The gate agent just laughed—politely, because Singapore Airlines staff are always polite—and directed him to check it.

At the end of the day, this policy is your friend, not your enemy. It helps you avoid baggage fees (carry-on is always free), saves you from lugging heavy bags through the airport, and makes your journey feel more like a light stroll. Next time you fly, try packing one less shirt. You’ll feel like a weight has been lifted—literally.

Remember: the right bag size means more time for a pre-flight cocktail at the Skyview Lounge, and less time wrestling with overhead bins. So roll up your favorite jeans, pack that Kindle, and enjoy the ride. Singapore Airlines has your back—as long as your bag fits in the sizer.
