- Is it possible to take more baggage weight than the allowance mentioned on the ticket? And how do I proceed?
Usually this is possible. Most airlines will allow you to take more as long as you pay an overweight fee.
It is usually also possible to take cumbersome objects. For sporting gear (golf bag, skis, surf board, bike, ?) and musical instruments (contrabass, cello, guitar, ?) most airlines charge a fixed fee.
Check your airline's website for further details.
