About this tool

The allowance applies to bag + contents; empty-bag weight is the forgotten 2–4 kg. The margin readout tells you exactly how heavy the airport scale will say you are.

Airline Baggage Allowance Table (Typical Economy Values)

Allowances change by route, fare class and loyalty tier, so always confirm on your booking — but the table below shows the typical economy-class published allowances travellers plan around in 2026. Use the calculator above with your airline's checked-bag limit to see exactly how much packing headroom you have.

Figures are typical published economy allowances for planning only; fare-family and route differences apply — always check your ticket.

Excess Baggage Fees: How the Maths Works

Airlines charge for excess weight in two ways. Weight-system carriers (most of Asia, Europe, Middle East) sell extra kilogram blocks — commonly 5–10 kg — priced per sector, and the per-kg rate at the airport is usually the highest you will pay. Piece-system carriers (US transatlantic) charge per extra bag instead, with overweight-bag surcharges on top when a single bag crosses 23 kg (50 lb). Buying allowance online in advance is almost always cheaper than paying at the counter, and pre-purchased blocks are sometimes 30–50% below airport rates.

• Weigh your packed bag at home — bathroom scales err by ±1 kg, so leave margin.
• Move 2–3 kg into cabin luggage where limits allow instead of buying blocks.
• Dense items (books, chargers, toiletries) cause most overweight surprises; redistribute them early.
• On code-share flights, the operating carrier's rules apply — check which airline actually flies the leg.
