Yes, you can bring a backpack with a carry on bag on most commercial flights. This is usually allowed as your personal item, provided it fits under the seat in front of you. You should verify your airline’s specific size limits before you head to the airport.
Can you bring a backpack as carry on
Most airlines allow you to bring one standard carry-on bag for the overhead bin and one smaller personal item to stow under your seat. A backpack is almost always accepted as your personal item if it meets the size requirements set by the carrier.
| Situation | Answer | Why |
|---|---|---|
| Backpack fits under seat | Yes | It counts as a personal item |
| Backpack is too large | No | It must fit in the bin |
| Airline has strict policies | Varies | Check the official baggage policy |
| You have two large bags | No | Only one carry-on is allowed |
| You’re flying basic economy | Yes | Personal items are usually included |
| You have a small laptop bag | Yes | It fits under the seat |
What decides if your bag is allowed
The decision depends primarily on the physical dimensions of your backpack rather than the type of bag. Airlines set these limits to ensure that all passengers can safely stow their belongings during takeoff and landing. If your backpack is small enough to slide fully under the seat in front of you, it’s considered a personal item. If it’s too bulky, the staff may require you to check it at the gate, which can lead to extra fees.
You can find the exact dimensions permitted by your airline on their official baggage policy page. Most major carriers define a personal item as something that fits within a specific footprint, usually around 18 x 14 x 8 inches. If your bag is within these limits, you’re safe; if it exceeds them, you must treat it as your primary carry-on or check it.
Steps to pack your bags for flight

- Measure your backpack size to ensure it stays within the airline’s personal item limit.
- Pack heavy items in your larger carry-on bag to keep the weight of your backpack manageable.
- Keep essential electronics like laptops or tablets in the backpack for easy access during security screening.
- Remove sharp objects or liquids over 3.4 ounces from your backpack before you reach the checkpoint.
- Check your bag’s fit by placing it under a chair at home to confirm it doesn’t stick out into the aisle.
The mistake people make when packing
The most common mistake is overstuffing a backpack until it becomes too rigid or tall to fit under the seat. When this happens, the flight crew may force you to gate-check the bag, which often costs money and delays your exit at the destination.
You can avoid this by leaving the top section of your bag slightly empty. This allows the backpack to compress easily if the space under the seat is smaller than expected. A simple squeeze test at home will tell you if your bag has enough “give” to be tucked away.
When to stop and get help
- If your backpack contains prohibited items like large tools or flammable liquids, you must remove them or leave them at home.
- If you require medical equipment that exceeds standard size limits, you should contact the airline’s special assistance desk.
- If you’re unsure about the weight limit for your specific fare class, check the airline’s website to avoid surprise fees.
Frequently asked questions
Can you bring a backpack with a carry on as a personal item?
Yes, you can bring a backpack as your personal item alongside a standard carry-on bag. Most airlines classify a backpack as a personal item as long as it fits under the seat in front of you.
What is the maximum size for a personal item?
The maximum size is usually around 18 x 14 x 8 inches, though this varies by airline. You should check the specific dimensions listed on your booking confirmation or the airline’s official website before you pack.
Does a laptop backpack count as a carry-on?
No, a laptop backpack counts as your personal item, not your main carry-on. You’re typically allowed to bring both a carry-on for the overhead bin and a smaller laptop bag for under your seat.
Is there a weight limit for a personal item?
Yes, some budget airlines have a combined weight limit for all carry-on items, often around 15 to 22 pounds. Check your airline’s baggage page to see if they specify a weight limit for personal items.
Can I bring a backpack and a purse?
Usually no, as most airlines count a purse as your one personal item. If you bring a backpack, you must fit your purse inside it to comply with the “one personal item” rule.
What happens if my backpack is too big?
If your backpack is too big, the gate agent may require you to check it as luggage. This can result in a gate-check fee depending on your ticket type and the airline’s current baggage policy.
Does it matter if my backpack has wheels?
No, it doesn’t matter if your backpack has wheels, provided the total size is within the allowed limits. However, wheeled bags can be harder to fit under seats due to the handle and frame.
Conclusion
Check your airline’s baggage rules on their website before you leave for the airport to confirm their specific size limits. If your backpack fits within these dimensions, you’ll have no trouble bringing it on board. Stop and ask for help at the check-in desk if your bag is clearly oversized.
