What size duffel bag can I carry-on United Airlines?

The United Airlines carry-on allowance permits you to bring one cabin bag at 9 x 14 x 22 inches (22 x 35 x 56 cm), plus one personal item with maximum total dimensions of 9 x 10 x 17 inches (22 x 25 x 43 cm).



For United Airlines in 2026, the standard maximum size for a carry-on duffel bag is 9 inches x 14 inches x 22 inches (22 cm x 35 cm x 56 cm), including handles and wheels. This bag must be able to fit in the overhead bin. However, it is crucial to check your ticket type; if you have booked a "Basic Economy" ticket on a domestic flight, you are generally not allowed a full-sized carry-on bag and are limited only to one "personal item" that fits under the seat in front of you. A personal item must be no larger than 9 inches x 10 inches x 17 inches (22 cm x 25 cm x 43 cm). Because duffel bags are soft-sided, they are often more forgiving than hard suitcases, but if you overstuff a 22-inch duffel so that it "bulges" beyond 9 inches in depth, a gate agent may require you to check it. To avoid fees, it is best to use a duffel with compression straps to keep it within the required dimensions. If you are flying on a United Express regional jet (the smaller planes), you may be asked to "gate-check" even a compliant duffel because the overhead bins are significantly smaller than those on mainline Boeing or Airbus aircraft.
