After reviewing Turkish Airlines' baggage regulations, I've come to the realization that I may need to acquire additional baggage allowance. How I can obtain extra baggage allowance?

The term "baggage allowance" describes the most luggage and personal items that a passenger may bring on a flight without being charged extra. The specific allowances can change depending on the airline, ticket class, and travel destination. It typically includes both carry-on (hand luggage) and checked baggage.
• Extra baggage sales are only for ticketed passengers. Validate your ticket before continuing.
• Sports equipment and musical instruments are not allowed as extra baggage.
• Turkish Airlines' online channels allow you to buy 3 kg or 1 piece of extra baggage up to 230 kg or 10 pieces. Each piece of luggage cannot exceed 32 kg and 158 cm in width, length, and height.
• The maximum weight for one piece of luggage on piece baggage routes is 23 kg for Economy Class and Business Class. Extra baggage between 23-32 kg costs 80 USD per piece on these routes.
• AnadoluJet flights with Turkish Airlines transit incur extra baggage fees and regulations. AnadoluJet baggage rules apply if your entire trip is on their flights.
• AnadoluJet is the only airline that allows online purchases of extra baggage for multi-airline itineraries.
• Extra baggage for infants is not available.
• Extra baggage sales may be limited by aircraft capacity.
