Checked bag fees are out of control. At this point, paying $35–$70 each way just to bring a suitcase feels like a tax on anyone who likes to actually pack. The good news? You can skip all of it. Traveling with just a carry-on and a backpack is completely doable — you just need to know how to pack smart and, more importantly, how to manage both bags without losing your mind at the airport.
Here's the exact approach we use.
1. Choose the right carry-on size
Most airlines allow a carry-on up to 22 x 14 x 9 inches. A hard-shell carry-on in that range gives you the most usable space without the risk of getting gate-checked. If you're flying budget carriers like Spirit or Frontier, double-check their specific dimensions — they're stricter.
2. Pack your carry-on for the overhead bin
Your rolling carry-on goes in the overhead, so pack it with anything that doesn't need to come out mid-flight: clothes, shoes, toiletries under 3.4oz. Use packing cubes to compress your clothes — you can fit a surprising amount into a 22" spinner when everything is rolled and compressed.
3. Pack your backpack for under the seat
Your personal item (backpack) goes under the seat in front of you, so this is where you want easy-access stuff: laptop, headphones, snacks, a jacket, your phone charger, and anything you'll want during the flight. Keep it under 18 x 14 x 8 inches to safely qualify as a personal item across most airlines.
4. Solve the two-bag problem at the airport
Here's where most people struggle. Rolling a carry-on with one hand and managing a backpack on your shoulder works fine — until you're rushing through a terminal, grabbing coffee, or navigating a crowded security line. Your backpack slides off your shoulder constantly, and you end up doing this awkward shuffle that makes you look like you've never traveled before.
The fix is attaching your backpack directly to your carry-on using a luggage strap. A good carry-on bag attachment strap wraps around both bags and holds your backpack securely against the back of your rolling suitcase. This gives you both hands free and turns two bags into one smooth unit you can roll through the airport without thinking about it.
The Roam Link is an adjustable luggage strap designed exactly for this. It fits over any backpack or duffel, attaches to your carry-on in seconds, and rolls up for compact storage when you don't need it. It works with every bag combination we've tested — oversized hiking packs, slim laptop bags, gym duffels, you name it.
5. Move through the airport like you've done this a thousand times
Once your backpack is locked onto your carry-on, you're hands-free. Grab your boarding pass, get your coffee, cruise through security without the juggle. When you land, unclip in 10 seconds and you're ready to move.
The bottom line
Traveling with just a carry-on and a backpack isn't about packing light — it's about packing smart. The right gear makes it effortless. Once you figure out your system, you'll wonder why you ever checked a bag.
