- Can I take outsize baggage (surf board, bike, contrabass, skis, golf bag,) ?
That depends. Some airlines offer this possibility others don't. Much depends on the aircraft type they use. On as small plane a surf board will usually not be accepted.
The best thing to do is to check in advance. If your really wish to take your surf board you had best check before you purchase your ticket because this may determine what company you will fly with.
Usually you will be asked to pay a supplement. Most airlines charge a fixed fee for sporting gear (golf bag, skis, surf board, bike?) and musical instruments (contrabass, cello, guitar, ...).
