Will the airline let my carry on luggage on?

Tom Bihn Aeronaut Luggage

Ever wonder if your bag will fit in the overhead bin of the plane you are about to fly on, or worse if the airline will allow your carryon bag onto the plane? Will they force you to check your luggage? This is why I have created the tool below. You can either select your luggage from the list of common manufacturers and models of luggage below, or you can measure the height, width and depth of your luggage and enter them in the boxes below. From there you can either select your airline, or leave the airline empty to see a list of airlines that will allow your luggage on as a carry on.

Or enter your bag’s dimensions

In centimeters and kilograms.

Leave it blank to see every airline that will take your bag.

This checks size and weight only, not whether the bag is included in your fare. easyJet, Ryanair, Wizz Air, Frontier and Allegiant include only a small under-seat bag for free, and many other airlines leave the overhead bag out of their cheapest fares.

How to Measure Your Bag

The easiest way to measure your bag is to lay it flat on its back. Looking down at it, the longer side is the height and the shorter side is the width. The depth is how far the bag stands up off the surface.

Why Airline Carry-On Limits Exist

Overhead bin space is finite. Most commercial aircraft have bins sized for a specific number of bags per row, and when everyone boards with a full-size carry-on, space runs out fast. Airlines enforce size limits to ensure bags physically fit, and to manage the boarding process when they don't.

What Happens If Your Bag Is Too Large

At the gate, an oversized carry-on gets checked, sometimes free, sometimes with a fee depending on the airline. The bag then travels in the hold and you collect it at baggage claim. On smaller regional aircraft the limits are often stricter than the airline's published policy because the overhead bins are genuinely smaller.

Size Limits Vary More Than You'd Think

Most major international airlines allow carry-ons up to around 56 x 45 x 25 cm (22 x 18 x 10 inches), but the exact dimensions vary. Budget airlines, especially in Europe, often have stricter limits and some charge extra for larger carry-ons entirely. Always check the specific airline's current policy before your trip. The tool above uses current verified dimensions for each airline in the list.

Tips for Carry-On Travel

  • Soft-sided bags can often squeeze into overhead bins even when slightly over the limit. Hard-shell bags cannot flex
  • Pack heavier items at the bottom to keep the bag balanced
  • Rolling clothes rather than folding compresses them and reduces wrinkles
  • Keep liquids in an accessible pouch to save time at security
