Yes, most airlines allow you to bring a personal item alongside your carry-on bag, meaning you can have a carry on suitcase and a backpack on almost every flight. This assumes the backpack fits under the seat in front of you.
Rules for your suitcase and backpack
You should verify your specific ticket class, as some budget carriers charge extra for overhead bin space. The following table summarizes how major carriers typically handle two-bag configurations.
| Your situation | Answer | Why |
|---|---|---|
| Standard economy ticket | Yes | Most allow one bag and one item |
| Basic economy (US) | Usually yes | Personal item is almost always included |
| Ultra-low-cost carrier | Sometimes | Often charge for overhead carry-on bags |
| Business class | Yes | Higher limits usually apply |
| Regional small jets | No | Overhead bins are often too small |
How airlines define personal items
Airlines generally define a personal item by its ability to fit under the seat in front of you. While dimensions vary by carrier, most airlines require these items to be no larger than 18 by 14 by 8 inches.
Packing for two bags
If you’re flying with both items, follow these steps to ensure a smooth boarding process.
- Pack the essentials in the backpack to keep your travel documents, medication, and electronics accessible.
- Measure your suitcase to confirm it meets the airline’s standard 22 by 14 by 9-inch limit.
- Check the gate requirements for your specific airline because some regional planes require all carry-on bags to be checked at the bridge.
- Place the heavier bag in the bin if you’re allowed two items, while keeping the backpack at your feet for easy access.
This approach isn’t for those traveling on “Basic” fares with airlines that strictly limit passengers to one bag total, as you’ll face high gate fees.
The mistake people make
People often ignore their backpack’s size. Always measure your packed bag to ensure it stays within the 18-inch height limit.
When to seek airline assistance
- Oversized items: If your bag exceeds the airline’s size limit, you must speak with a gate agent early.
- Medical devices: If you have a CPAP machine or other medical equipment, check the airline’s disability policy before you arrive at the airport.
- Weight limits: If your bag weighs more than 20 pounds, some international carriers may restrict it.
- Flight changes: If you’re rebooked on a smaller aircraft, you may lose your overhead bin access.
Can I bring a laptop bag and a backpack?
Yes, most airlines count a laptop bag as your personal item. If you have both, you must fit the laptop bag inside your backpack or consolidate them into one container.
Does a duty-free bag count as a second item?
Usually no, as most airlines allow a duty-free shopping bag in addition to your carry-on and personal item. Check your airline’s specific policy before purchasing items at the gate.
What happens if my backpack is too big?
If it doesn’t fit, the agent will require you to check it. This results in a gate-check fee and baggage claim retrieval.
Is it safe to put my backpack in the overhead bin?
Yes, it’s safe, but you must move it to the floor during takeoff and landing. The crew will ask you to relocate the item if it blocks the bin’s closure.
How long does it take to clear security with two bags?
It doesn’t take longer to clear security with two bags, but you must remove your laptop from your backpack. Ensure your electronics are easily accessible to keep the line moving.
Do I have to pay for a personal item?
No, personal items are included with almost every ticket type. Only your carry-on suitcase is subject to extra fees on restricted or basic economy tickets.
Can I wear my backpack while boarding?
Yes, you can wear it while boarding, but you must remove it to navigate the aisle. This prevents you from hitting other passengers or overhead bins as you walk.
Check your airline’s website before your flight to confirm carry-on dimensions. If you can’t find your specific baggage allowance online, contact the airline’s support line to avoid unexpected fees at the gate.
Have carry, in short
Before you head to the airport, check your airline’s website to confirm their specific size limits. It’s a smart move to pack your heaviest items in your carry-on so your backpack doesn’t feel too bulky. You’ll have a much smoother journey when you aren’t struggling to lift your bags into the overhead bin.
