An overweight, oversized, odd-size baggage is a piece of luggage or an item that exceeds the standard baggage weight and size set by the airline(s). For example, a bag over 23 kg (50 lb) and 70 kg (32 lb) (depends on your allowance and certain routes), longboards for surfing and larger musical instruments will all fall into this category.
