In 2026, Flixbus has become significantly stricter with luggage enforcement to maintain their tight turnaround schedules. Every passenger is allowed one piece of "Travel Luggage" (max 20kg / 44 lbs) to be stored in the hold and one piece of "Hand Luggage" (max 7kg / 15 lbs) to be kept under the seat or in the overhead rack. Drivers now frequently use handheld digital scales and "sizing frames" at major hubs like Berlin, Paris, and New York. If your bag exceeds the dimensions or weight, you will be charged an "Excess Luggage" fee on the spot, which can be as high as €15-€25 per item, and you may even be denied boarding if the hold is completely full. For 2026 travelers, it is highly recommended to "Pre-book" an extra bag online for a much lower fee (around €5) if you suspect you are over the limit. Unlike airlines, Flixbus drivers are the final "gatekeepers" of the policy, and while some may be lenient on quiet routes, they are generally uncompromising during peak holiday periods and on popular cross-border routes.
