At Comair we are issued only the airports that we fly into. (Scheduled destinations plus maintenance bases.) When we do a charter, we are given a charter packet that includes jepps for any offline airports. We also have a "brick" packet that stays in each airplane that includes offline alternate airports. This really cuts down on the number of plates that we carry.

The only thing we are required to purchase are the jepp binders if you buy them from the company. Of course, you can always bring your own.
