What is considered a carry-on bag on a bus?

The typical size of the overhead compartment in buses is 9x16x20 inches (22.8?40.5?50.8 cm). So, bringing a small suitcase along as a carry-on bag weighing no more than 25 lbs (12 kg) is perfectly fine. Make sure you put your valuables into your carry on or carry them on you to be safe.



For 2026 bus travel (on carriers like Greyhound, FlixBus, or National Express), a carry-on bag is defined as any luggage small enough to fit in the overhead rack or under the seat in front of you. The standard size limit is approximately 18 x 14 x 8 inches, which is slightly smaller than the standard 22-inch airplane carry-on. Most bus lines are quite strict about this because the overhead racks on coaches are often very shallow and narrow. Items like backpacks, small duffel bags, or laptop cases are the ideal 2026 carry-on choices. If your bag exceeds these dimensions or weighs more than 15–20 lbs, the driver will likely require you to "check" it in the luggage bay under the bus. A "pro-tip" for 2026 is to always keep your valuables (ID, wallet, electronics) in your carry-on, as the under-bus storage is not climate-controlled and is generally accessed at every stop by multiple passengers.
