Carry-On Weight Limits by Airline (2026)

Check the weight model before adding a second bag

A per-piece cap and a combined cap answer different questions. Under KLM's published 12 kg Economy allowance, a 9 kg main bag plus a 4 kg small bag totals 13 kg and fails the combined limit. The main bag must also be included in the booked fare. A separate per-piece cap, where published, still applies even when the total is within the shared cap.

In the bag checker, select Check both bags together, enter each packed weight and choose the actual fare. The route checker repeats that check for each operating airline. An unknown weight model or missing weight stays unresolved; the tool does not assume the personal item is extra free weight.

Weight is only one part of cabin-bag eligibility. Your packed bag must meet the airline's size rule, and your ticket must include the type of bag you want to bring. The British Airways row was reviewed on 28 September 2026; other rows retain their 23 September review. Follow the source link for your specific fare and operating flight.

Read “no stated limit” carefully

It means the cited policy page does not give a numerical maximum for the overhead bag. It does not waive dimensions, bag-count rules or the requirement to lift and stow the bag safely. A carrier or partner operating the next leg may apply a different policy.

Check the whole itinerary

Weigh the packed bag, measure it including wheels and handles, and compare it with each flight's fare. For example, an Air New Zealand Premium Economy passenger cannot split 20 kg evenly between two cabin bags: the combined allowance is 14 kg. Likewise, a bag weighing less than Ryanair's 10 kg Priority limit still needs the Priority allowance and must fit the 55 × 40 × 20 cm box.

Use the bag fit checker for dimensions and weight, then confirm fare benefits and exceptions on the airline's booking page. For a multi-airline trip, the most restrictive segment may determine what you can bring without checking a bag.
