In 2026, the "rule of handbag" in aviation refers to the weight and dimension limits for carry-on items that a passenger can bring into the cabin for free. While policies vary by airline, a common standard (such as that used by carriers like IndiGo or Ryanair) allows for one handbag up to 7 kg with maximum dimensions of 115 cm (L+W+H). Additionally, many airlines permit a second "personal article"—such as a small ladies' purse, a laptop bag, or a camera bag—provided it does not weigh more than 3 kg and can fit comfortably under the seat in front of you. This "two-item" rule is designed to ensure overhead bins do not become overstuffed and to facilitate a faster boarding process. For 2026 budget travelers, it is vital to pre-weigh these items, as "Gate No-Shows" or over-limit bags can result in significant fees (often $50 or more) if the bag must be checked at the last minute.
