Books
Surprisingly, branches of Choithrams supermarkets randomnly stock copies of Aircraft Illustrated, Flight International, Airliner World and Aviation News.
Try, especially, the branches at Garhoud (behind Le Meridien hotel, near the airport) and - rather far away but most likely - Choithrams at the Green Community, Dubai Investments Park (next door to the Courtyard by Marriot lodge).
Good luck.
