iPad Air Now Shipping 'Within 24 Hours' in U.S., Pushing Delivery Estimates to November 6

Launch day supplies of the iPad Air in the U.S. appear to be dwindling slightly, with new orders of the tablet in all colors and capacities shipping within 24 hours and carrying a delivery estimate of November 6.

When the iPad Air launched on November 1 at 12:01 AM Pacific Time, Apple declined to provide a shipping estimate, instead offering a blanket November 4 delivery date for all U.S. orders.

Earlier this morning, in-store supplies of the iPad Air of began weakening at some retail locations, and the T-Mobile Space Gray 128 GB Wi-Fi + Cellular iPad Air was the first model to see its shipping time slip to 5 to 10 business days.

Other countries around the world have also seen dwindling supplies, with some countries seeing 5–10 day shipping times for certain models. Higher capacity iPads and the Space Gray models appear to be selling out the fastest.

Though some stores are seeing less availability of higher end models, in-store supply of the 16 and 32 GB iPad Air remains strong in most areas. Prospective iPad Air buyers in the United States can use Apple-Tracker.com to check on local availability of the iPad Air.
