AHLprovides900 points (flight miles) for each flight to its customers flyingfrom Istanbul to Ankara. However, it gives 1000 (flight miles)extra points to more than 3 flights and 1350 (flight miles) to morethan 6 flights within three months. While OA gives 1200 points(flight miles) for each flight, it gives 1500 (flight miles) extrapoints for every 5 flights within three months.
