what is the difference between an ipad air 2 and 3?
Display. The iPad Air 2 has a 9.7-inch display (2048×1536 resolution at 264 ppi) whereas the display of the iPad Air 3 has been bumped up to 10.5-inch (diagonal) with a 2224×1668 resolution (264 ppi). With the 10.5-inch display, the new iPad Air actually seems like a lighter version of the iPad Pro.
