Porter Airlines Carry-On Size & Baggage Rules (2026)
If you’re flying with Porter Airlines for the first time, their carry-on rules can feel a bit different compared to larger international carriers. Porter has specific policies around carry-on size, luggage dimensions, weight limits, and cabin baggage allowance—and these can change depending on your fare type. Knowing the exact carry-on size, personal item rules, and baggage restrictions upfront can save you from surprises at the gate.
Porter Airlines Carry-On Luggage Size & Weight Limits
| Baggage Type | Size (cm) | Size (inches) | Weight | Allowance |

Porter Airlines Carry-On & Baggage Fees
Porter Airlines does not publish fixed carry-on baggage fees on this page. However:
| Baggage Type | Price Range |
|---|---|
| Personal item | Included |
| Carry-on bag | Varies by fare (included or not included) |
| Checked bag | Varies by route and booking time |
Carry-on bags are not included in Basic fares, meaning you may need to pay to check them.

Carry-On Dimensions & Size Restrictions for Porter Airlines
Porter Airlines has clearly defined size restrictions for both cabin baggage types.
- Carry-on luggage size: 55 x 40 x 23 cm
- Personal item size: 33 x 43 x 16 cm
Your bag must fit within these permitted dimensions and also fit into the airline’s sizing units at the airport. These are available at both check-in counters and boarding gates.
Porter is quite clear about storage too. Your baggage must fit:
- In the overhead bin, or
- Under the seat in front of you
If your bag exceeds the allowed size or cannot be safely stored, it won’t be allowed in the cabin.
When comparing Porter Airlines to other carriers, you’ll notice its fare-based carry-on policy stands out. For example, airlines like Flair Airlines carry-on size rules and Ryanair cabin baggage limits are stricter when it comes to paid allowances. Meanwhile, WestJet carry-on size limits offer a more traditional baggage setup similar to Porter’s higher fare classes.
Porter Airlines Carry-On Weight Limit & Baggage Allowance
Interestingly, Porter Airlines does not specify an exact weight limit for carry-on baggage.
Instead, the focus is on:
- Whether you can safely lift and store your bag
- Whether it fits within size restrictions
Baggage allowance depends on your fare:
- Basic fare:
- 1 personal item only
- No standard carry-on bag included
- Standard, Flexible, Freedom, Navigate, Ultimate fares:
- 1 personal item
- 1 carry-on bag
This fare-based allowance is one of the most important things to check before your flight.
Personal Item Size & Carry-On Bag Allowance
Every passenger can bring one personal item onboard.
Accepted examples include:
- Laptop bags
- Small backpacks
- Purses or handbags
- Camera bags
- Small garment bags
The personal item must fit under the seat and stay within the defined size limit.
If you’re traveling on a higher fare class, you can also bring a standard carry-on bag in addition to this.
Carry-On Size Restrictions & Rules
Porter Airlines enforces several key carry-on restrictions:
- Bags must fit within size limits and storage areas
- Oversized items may be checked at the gate
- Additional restrictions may be applied at the airport without notice
- All bags must pass through sizing units before boarding
There’s also a unique rule:
If your bag cannot be safely stowed, Porter may require it to be checked—even if it technically meets size requirements.
If you’re unsure what qualifies as cabin baggage, it helps to understand the basics first. This guide on what counts as carry-on luggage explains what you can bring onboard. You can also explore the difference between carry-on vs personal item to avoid confusion at the gate, especially since Porter allows both depending on your fare.
Maximum Carry-On Size Allowed by Porter Airlines
The maximum allowed carry-on size is:
- 55 x 40 x 23 cm (21.5 x 15.5 x 9 inches)
This includes handles and wheels.
Anything larger than this is considered oversized and won’t be allowed as cabin baggage.
Getting your bag size right is key before heading to the airport. Many travelers mix up units, so this breakdown of carry-on size in cm vs inches can help you measure correctly. You should also check general carry-on weight limits across airlines, since Porter doesn’t clearly define weight but still expects manageable baggage.
How Strict Is Porter Airlines With Carry-On Size?
From real traveler experiences, Porter Airlines tends to be moderately strict.
Here’s what you can expect:
- At smaller airports (like Toronto City Airport), staff often check bag sizes more closely
- Gate agents may ask you to use sizing units
- If the flight is full, enforcement becomes stricter
However, they’re not as aggressive as ultra-low-cost airlines. As long as your bag looks compliant and fits properly, you’ll usually be fine.
Carry-On Rules for Domestic vs International Flights
Porter Airlines applies the same carry-on size and baggage rules across:
- Domestic flights within Canada
- Flights to/from the United States
However, there’s one important difference when using GatePorter service (explained below), especially on U.S. inbound routes.
For international trips, rules can feel slightly different depending on security checks and airport procedures. This guide on international carry-on size rules gives a broader view of what to expect. Also, if you’re packing toiletries, reviewing carry-on liquid size restrictions will help you pass through security without delays.
What Happens If Your Carry-On Exceeds Size or Weight Limits?
If your carry-on exceeds the allowed size:
- It will be checked at the gate
- You may need to pay a fee
Also:
- Oversized items cannot be GatePortered
- You won’t be allowed to carry them into the cabin
Porter also reserves the right to check your bag even if:
- Cabin space is limited
- The item cannot be safely stored
Carry-On Allowance by Fare Class (Economy vs Business)
Porter Airlines doesn’t have traditional “business class,” but fare types work similarly.
Basic Fare:
- 1 personal item only
- Carry-on bag not included
All Other Fares:
- 1 personal item
- 1 standard carry-on bag
This is one of the biggest differences compared to full-service airlines.
Additional Carry-On Rules & Special Allowances
Porter includes several useful exceptions:
Items NOT counted toward baggage allowance:
- Coat or jacket
- Umbrella
- Cremated remains
- Life-sustaining medical containers
Infant allowance:
- If traveling with an infant (under 2), you can bring a diaper bag in addition to your normal allowance
Medical and mobility devices:
- Wheelchairs, CPAP machines, and assistive devices are allowed free of charge
GatePorter Service (Unique Feature)
Porter offers something called GatePorter service.
Here’s how it works:
- You leave your carry-on at the aircraft bridge before boarding
- It’s stored in the cargo hold
- You collect it at arrival (either at the gate or baggage carousel depending on route)
Important notes:
- Remove valuables (laptop, medication, documents)
- GatePortered bags must still follow size restrictions
- On some U.S. routes, bags go to baggage claim instead of the gate
Liquids & Security Rules
Porter follows standard airport liquid rules:
- Max 100 ml per container
- All liquids must fit in a 1-liter transparent bag
- Only one bag per passenger
Exceptions apply for:
- Medications
- Baby food
- Special dietary items
Duty-free liquids over 100 ml are allowed if sealed properly.
If you’re deciding between airlines, comparing policies side-by-side can make things clearer. For instance, this comparison of American Airlines vs Delta carry-on size highlights how different airlines handle baggage rules. It’s useful if you’re wondering which airlines are stricter with carry-ons or what happens if your bag is too big.

Final Thoughts
