IPad air2 are they still being made?

No. The iPad Air 2 was replaced last year by the iPad 5th generation.

The current iPad 6th generation is the replacement to that 5th generation.

No but they are similar.

Unboxed ones can still be bought through Amazon though!

IPad Air 2 models were discontinued in Aug/Sep 2016.

The iPad Air 2 was introduced in Oct. 2014. These iPad models are almost 4 years old, now.

The ONLY older iPad model still being produced is the iPad Mini 4.
