iPad Air Online Orders Go Live in the United States, Canada, and Europe
The iPad Air, available in space gray/black and white/silver can be purchased directly from Apple via the Apple Online Store and through the Apple Store iOS App. [Direct Link] The Apple Store app is often the most reliable way to place an order, as it circumvents web traffic. For the first time ever, Apple is accepting Personal Pickup requests in the U.S., allowing customers to reserve an iPad Air online for pickup at a local retail location.
Initial orders from the Apple Online Store will ship within 24 hours for all colors, carriers, and capacities in Canada and Europe. U.S. online orders list a delivery date of 11/4 rather than a shipping estimate.
