Yes, you generally can carry a backpack and a carry on when you fly. This assumes your airline doesn’t have strict policies limiting passengers to one total item, so check your specific ticket type before heading to the airport.
Rules for a carry-on and backpack
Most airlines allow one carry-on bag and one personal item, which is where your backpack fits in. The personal item must be small enough to fit under the seat in front of you.
| Your situation | Answer | Why |
|---|---|---|
| Standard economy ticket | Yes | Most carriers allow two items |
| Basic economy fare | Often no | Some airlines restrict personal items |
| Regional small planes | Maybe | Limited overhead and under-seat space |
| Business class ticket | Yes | Higher limits usually apply |
| Budget airline flight | Check rules | They often charge for overhead bags |
| International long-haul | Yes | Standard two-item allowance applies |
What decides the allowance
The main factor determining your total allowance is the specific fare class you purchased. Budget airlines often sell “Basic Economy” tickets that restrict you to only one item, meaning you must pay extra to bring both a backpack and a rolling suitcase. If you have a standard ticket, the rule is usually one carry-on for the overhead bin and one personal item for the floor.
Space is the secondary constraint, especially on smaller regional jets. These aircraft have smaller overhead bins that can’t fit standard carry-on suitcases. If you’re flying on a plane with fewer than 50 seats, the crew may require you to gate-check your larger bag regardless of your ticket type.
Always verify your specific airline’s carry-on baggage policy on their official website to ensure your bags meet their size limits. If your total combined weight exceeds the limit for your class, you must check one bag; if your backpack fits under the seat, you can keep both.
How to organize your gear

If you’re bringing both items, follow these steps to move through the airport quickly.
- Measure your bags before leaving home to ensure they meet the airline’s dimensions. Most airlines require a personal item to be roughly 18 x 14 x 8 inches.
- Pack heavy items in your smaller backpack so it stays manageable under the seat.
- Keep essentials like your passport, wallet, and phone in the backpack. This ensures you have them even if the gate agent forces you to check the larger bag.
- Use a luggage strap to secure your backpack to the handle of your rolling carry-on. This makes walking through the terminal much easier.
- Board early if you have a large carry-on to ensure you find space in the overhead bin.
The mistake people make
The most common mistake is assuming that a “carry-on” and a “personal item” are the same size. People often try to bring two large bags into the cabin, which forces the gate staff to check the second bag at the last minute.
This creates a risk of damage and often results in a significant fee at the gate. You avoid this by verifying the dimensions on your airline’s website and ensuring your backpack is small enough to slide easily under the seat in front of you.
When to stop and get help

You should stop trying to handle both bags yourself if you encounter these signs:
- The gate agent identifies your bag as too large, which requires a gate check.
- You can’t lift your bags into the overhead bin, which risks injury to yourself or others.
- Your items exceed the weight limit set by the airline, which leads to extra fees.
If you have a mobility issue or can’t lift your luggage, ask a flight attendant for assistance before boarding.
Frequently asked questions
Can I bring a laptop bag and a backpack?
Yes, you can bring both if one fits under the seat. Most airlines count your laptop bag as your personal item and your backpack as a secondary bag, provided it meets carry-on size limits.
How long does it take to clear security with two bags?
It takes about 5 to 10 minutes longer to clear security with two bags. You must remove your laptop and liquids from both, so organize your gear to keep these items easily accessible.
Is it safe to put a backpack under the seat?
Yes, it’s safe, but you must ensure it doesn’t block the aisle. Place it fully under the seat in front of you to comply with safety rules regarding emergency exits.
What happens if my bag is too big?
Your bag will be gate-checked if it’s too big. You’ll likely pay a fee at the gate, and the bag will be placed in the cargo hold for the flight.
Does it matter if I fly a budget airline?
Yes, it matters greatly because budget airlines have stricter rules. Check your specific ticket, as some budget carriers charge for every item that doesn’t fit in your pocket.
How many bags can I bring on a plane?
You can bring two bags, which consists of one carry-on and one personal item. This assumes you’re flying a standard fare that permits both pieces of luggage in the cabin.
Can I carry a backpack and a carry on if I have a flight connection?
Yes, you can keep both bags during a connection. Ensure your backpack is comfortable to carry, as you’ll be responsible for moving both items between gates during your transit.
Conclusion
Start by checking your airline’s website for the exact dimensions allowed for your specific fare class. You should expect to breeze through security if your gear is organized and meets these sizes. If you can’t lift your bags safely, ask a ground agent to check them immediately.
