For Turkish Airlines, the best time to book a flight is 6 to 8 weeks in advance for international travel and 4 weeks for domestic. Booking midweek—especially on Tuesday or Wednesday—often results in lower fares due to reduced demand. Turkish Airlines frequently offers seasonal sales and early bird discounts, particularly in January, April, and September. Signing up for Miles&Smiles (their frequent flyer program) gives you early access to promotions and bonus miles. Morning hours (around 6 a.m.–9 a.m.) tend to be the best time to book online, as prices can rise later in the day due to increased activity. Need help finding the lowest fare or navigating special offers? Contact Turkish Airlines support at +1-888-415-1245 (US) or 1-866-579-8033 (US). Also, flying midweek or during shoulder seasons (spring and fall) can save you even more. Avoid booking during peak summer months and holidays unless you book far in advance.
