Comparison
A 9 kg cabin bag is within allowance on the first carrier and 2 kg over on the second. On a separate ticket, the stricter rule applies to that leg regardless of what you cleared earlier.
How the Baggage Allowance Comparison works
- List every airline on the itinerary, including codeshare operators — the operating carrier's rules usually apply.
- Enter your bag's real dimensions with wheels and handles, which is what a sizer measures.
- Plan to the strictest allowance on the itinerary, since clearing one airport does not clear the next.
FAQ
Which airline's rules apply on a connecting flight?
Generally the operating carrier for each leg, though a single ticket sometimes applies the first carrier's allowance throughout. On separate tickets, each leg's rules apply independently — which is the case that catches people out.
Do dimensions include wheels and handles?
Yes, almost always. Sizers at the gate measure the bag as it is, and a bag advertised as cabin-sized can fail once its wheels and external pockets are included.
Why is being checked at the gate worse?
Because gate fees are typically much higher than pre-paid checked baggage, and payment at the gate is stressful and sometimes cash-only. Pre-paying is nearly always cheaper if you suspect you are over.

Baggage Allowance Comparison plans to the strictest leg, because clearing the first airport tells you nothing about the connecting carrier's sizer.
