Интересны, конечно, нюансы перевозки великов в самолете.

The additional allowance of 5 kg applies only and exclusively to the transport of sporting material, this being understood as all equipment used for practising sports: diving, surf or boogie equipment, wind or kite surfing, parachuting, golf equipment, bicycle equipment and skiing equipment.
There is no limit as to the weight or number of items for sports equipment.
The total weight of the sports equipment will be deducted from the normal allowance for the tariff or the customer’s condition as a BinterMás Gold or BinterMás Silver customer as well as the additional 5 kg for sports equipment.

Это значит, что бесплатно, если суммарный вес sport equipment и чумодана не превышает 20+5 кг?
