Did Carry-On Rules Change for 2026?
Over the past few weeks I have been seeing an increasing number of social media posts surrounding the carry-on size rules for flights in 2026. Since we love travel and I am a notorious over-packer, I went down this particular rabbit hole and got all of the information so you don’t have to. Before we get into it I want to say there is an unsurprising lack of information on airline websites regarding consequences for an oversize carry-on bag, but I will share what I have gathered to help you from finding out the consequences the hard way.
Did the Rules Actually Change?
The short answer is no. What actually changed was the airlines stating they were going to start heavily enforcing the rules for carry-on size which currently sits at 22”x14”x9” for most airlines. From what I can tell these sizing rules have technically been in place for a long time, just not enforced as long as your bag fit in the overhead bin. The most important thing to know is that the dimensions include all external components, not just the box of the suitcase itself, and they can vary from airline to airline. This means all handles, wheels and supporting feet are included in the dimensions. Whether or not your current carry-on meets the requirements could depend on the airline you are flying with.
Airline Information
I looked at Delta, American and United airlines’ websites to see what I could find out about their carry-on policies and what the consequences could be for bringing an oversize carry-on to the gate. In researching carry-on policies there were a lot of similarities between the three airlines;
One carry-on item and one personal item are included with your flight. This does depend on your ticket class and flight size as smaller size flights and certain ticket classes only include a personal item.
Standard carry-on size is 22”x14”x9” including all external components.
A bag checked at the gate due to inadequate overhead bin space is free of charge.
While all of the requirements for a carry-on are listed on the websites, there is nothing about what could happen if you show up to the gate with a bag that does not meet those requirements.
There are also quite a few differences between the airlines. Delta and United both have a free baggage calculator on their website for transparent baggage pricing. You can even put in your specific flight information to see exactly what your baggage pricing would be for different options. This could help you decide if it would be cheaper in the long run to check your bag versus purchasing a new suitcase to carry on. I could not find a baggage calculator on the American Airlines website. I also want to touch on the price of your first checked bag for each airline; Delta $45, United $50, American $30. I know we are talking about carry-on bags here, but stay with me because this number could be important later.
As previously stated, none of the websites list consequences for bringing an oversize carry-on to the gate, however; there are plenty of stories and speculation online. I saw the most stories about American Airlines and how passengers have had to pay to check their bags at the gate. According to these stories, passengers are charged the $30 fee plus a $25 gate fee to check their bag. Why? We can speculate that since there are no specific consequences listed for oversize carry-on bags, it is left up to the airlines to decide in the moment. There are similar stories for United though not nearly as many. Keep in mind that United has the highest checked bag fee of $50. If they add an additional $25 gate fee, you could pay $75 to gate check your bag with United. I was not able to find any stories about Delta charging fees to check oversize bags, but that doesn’t mean it hasn’t or can’t happen. I want to make very clear that this information comes from people telling their personal stories online and cannot be verified by me in any way.
What I want everyone to understand is that since there are no clear rules surrounding consequences for an oversized carry-on, it can change from day to day or staff member to staff member. You could end up paying a lot more to check your oversized bag at the gate versus checking it ahead of time or purchasing a new carry-on bag that meets the requirements. My motto is plan for the worst, hope for the best.
What does this Mean for You?
Here are a few things to keep in mind moving forward;
Check what baggage is included in your ticket fare when booking. If you are planning to take a carry-on, make sure it’s included on your flight. Checking both your ticket class and flight size will help you determine if a carry-on is included.
To avoid potential extra fees at the gate, purchase a size-compliant carry-on bag or check your bag upon checking in for your flights.
Shop for luggage in person and take a measuring tape so you can be absolutely certain the bag meets the carry-on requirements.
If shopping online for luggage, be very cautious about the listed measurements or the words “carry on compliant” in the listing. The dimensions may not include all external parts of the luggage which would not actually make the luggage compliant.
When in doubt, just check your bag. I know the fee may hurt a bit, but you could pay less up front than at the gate with certain airlines. This is especially important if you had to open the expansion on your suitcase, making it no longer size-compliant.
Conclusion
While the carry-on size didn’t actually change, enforcement did. I highly recommend that you measure your current baggage to see if you are compliant. Since I will be needing a new carry-on bag, check back later for a review of the viral garment duffel bag to see if it’s worth the purchase. Please let us know if you have a bag you love that still meets the size requirements!
Until Next Time,
Happy Travels
