Wow, you are able to purchase almost 2 roundtrips flying with TK via IST, booked in D-class.
Insane prices.

Looking at flights from LAX to FRA on 4/21, return on 4/29. 'Basic Plus' ($12347.46) and 'Flex' ($10892.46) both book into C but the less expensive Flex offers free rebooking and cancellation. Is this a glitch?
