How is the overage fee calculated?+
The calculator compares your bag's actual weight or dimensions to the airline's free allowance, then applies the airline's fee schedule to the excess amount, which is often tiered rather than charged per unit.
Why do fees jump sharply at certain weight thresholds?+
Airlines typically charge in fixed bands (for example, one fee for a bag 1-10 kg over the limit and a much higher fee beyond that), so being just 1 kg over a threshold can cost the same as being 9 kg over it.
Does exceeding both weight and size limits cost more?+
Some airlines charge separate fees for oversize and overweight violations, meaning a bag that breaks both rules can incur two separate charges rather than one combined fee.
Is it cheaper to pay for an extra bag or to redistribute weight?+
It depends on the fee structure: if you're traveling with others, shifting a few kilograms into another checked bag under its limit is often free, while a single overweight bag can trigger a costly per-threshold fee.
Do overage fees differ between online prepayment and airport payment?+
Yes, most airlines charge significantly more for excess or extra baggage paid at the airport counter than for the same service purchased in advance online, so checking ahead is usually the cheaper option.
