It's uncertain why the Frequent Flyer scheme was given such a dreadful name. It could be incase Lufthana's Miles & More wants to take it over at some point in the future. One thing is for sure - the name is as dreadful as when it was created
The Turkish Airlines Miles and Smiles programme is similar to most other Frequent Flyer schemes, with slight lower levels of mileage needed for elite status than other schemes, but with the nasty hangover that miles not used within three years expire, and are gone for good, and with a real sting in the tail that at the basic level, you still need to fly quite a lot to even retain membership. If you live in Turkey and plan to take several long haul trips a year, Miles and Smiles may be the scheme for you. If you do not, it definitely isn't, and there are better schemes around.
The worst part of Miles and Smiles is the Mile Expiry date. Miles earned on Turkish Airlines' Miles and Smiles program remain valid for three years. There are no extensions available. Once the miles expire they are lost.
Joining is easy; it's possible to do it online, although the joining process is convoluted with three pages of forms to fill in, and various bits that are mandatory that are not made clear. You get a membership number as soon as you sign up, however you don't get a 'real' card until you've flown on Turkish Airlines at least once.
Business Class Turkish Airlines Boeing 777
The perks at this level last for two years, but really only are useful if you are flying on domestic flights, where you can check in at the Business counter, and access the Business Class (CIP) lounges at Adana, Ankara Esenboga, Antalya, Bodrum, Dalaman, Gaziantep, Istanbul, Izmir
You also gain an extra 10kg of luggage allowance on both domestic and international flights.
Of course the real benefit of this level is that it comes with Star Alliance Gold status. That means access to the business class lounges, even when you are travelling in economy. Plus there is a 20kg of extra luggage allowance.
If renewal looks like being a problem, you can also buy your way in, so long are you are already at this level, purchasing up to 10.000 Status Miles for Elite membership renewal, however with 1000 miles costing 30EUR, it can be 300EUR just to get over the 27,500 threshold in 2 years. Again, there are easier and cheaper schemes.
To qualify, the member must have flown 80,000 miles in a 12 month period of time. To retain Elite Plus status, the member must collect 40,000 points or miles in the first year of membership, or 60,000 within the first two years of membership.
The only real tangible benefit over Elite is that there is 5kg more luggage - giving 25kg extra or 1 additional piece of baggage on flights with apiece concept, plus Free Upgrades from economy to business (twice in a year), a complimentary Elite Card for a friend or spouse, and you get to go through the special security entrance in Ataturk Airport for International departures which is normally reserved for politicians or friends of the pilot. In Turkey this is seen as a real benefit indeed.
