As noted by AppleInsider, MacBook Air supplies are beginning to dry up as Apple's annual Worldwide Developers Conference approaches.

Currently, the 13.3-inch 256GB 1.8Ghz MacBook Air is out of stock at Amazon.com, with a listed one to two month waiting period. While the low end 13.3-inch MacBook Air is in stock, the 11.6-inch MacBook Air is in short supply. Amazon lists an inventory of just ten 1.7Ghz 128GB 11.6-inch MacBook Airs and just one lower end 64GB 11.6-inch MacBook Air available through a third party.



Several other authorized Apple resellers, such as MacConnection, MacMall, and B&H, are also seeing dwindling MacBook Air inventory, with the higher end versions of 13.3-inch MacBook Air being the hardest to find.

Low inventory supplies at third-party Apple retailers are often one of the initial signs of an upcoming product refresh. According to KGI Securities analyst Ming-Chi Kuo, Apple will be introducing new MacBook Pro and MacBook Air lines based on Intel's Haswell processors at WWDC, which takes place next month from June 10 to June 14.
