Crowded. If you come by car, there are convenient paid parking lots, but the price bites, the car was in the parking lot for about 20 minutes and paid 30 dirhams. Clear pointers, clear lining.
Be sure to check which terminal is on the ticket. Different companies fly to Moscow from both terminals 1 and 3.
Good duty free service. You can buy souvenirs, sweets and alcohol at good prices.
