Newark Liberty Terminal A

[roadman65]

Am I to understand that the original A building will soon be demolished?

Also Satellite imagery shows both old and new still in use with gates 10-18 satellite being removed. 

I also noticed the new building only houses 28 gates, that is less than what the 1973 terminal once has which sounds odd.

Demolition of the old Terminal A has probably already started (but I can't find evidence).  The final arrangement of the new Terminal A requires some of the space occupied by the old Terminal A.  Completion of the remaining 5 gates in the new Terminal A is scheduled for later this year (2023), raising the final count to 33 gates.
