Miles&Smiles is the frequent flyer and loyalty program of Turkish Airlines, Turkey's flagship carrier. Launched in 2000, the program offers a range of benefits to its members, allowing them to earn and redeem miles for various travel-related rewards. Members accumulate miles not only through Turkish Airlines flights but also through flights operated by Star Alliance member airlines and other program partners, as well as through credit card spending and affiliated services. The program features a tiered structure, with different membership levels such as Classic, Elite, Elite Plus, and Elite Plus Privé, each providing escalating privileges including lounge access, extra baggage allowance, and priority check-in. Miles&Smiles members can use their earned miles for flight tickets, seat upgrades, hotel stays, and more. The program underscores Turkish Airlines' commitment to customer loyalty by offering a comprehensive and rewarding travel experience for its frequent flyers.
