Next month, we will be connecting from a domestic DL flight to int'l Turkish flight (TK32) in Atlanta. They are on separate tickets and we will have checked bags.

I assume we will need to exit the secure area to collect bags, then must check-in/check bags with Turkish. I already understand the hazards of separate tickets, but want to be fully informed so we don't waste valuable time figuring out how to make the connection. We have allowed 3 hrs.

According their website (and other sources) THY uses "Terminal N - Domestic (North)" However, the ATL terminal map does not show a THY check-in desk there, however is shows one in the International Terminal. Google maps shows them in the International Terminal as well. Since Delta supposedly has all of the Domestic South, if Turkish is located in the Domestic terminal it should be on the North side, but it is not listed (too small a presence?).

So, where is/are THY check-in desk(s)?
Will I need to collect our bags, take a shuttle to the International Terminal, to check in, then go through security again?
Or will I be lucky and be able to collect bags in the Domestic Terminal, go upstairs and check in/ check bags with THY before going through security to our gate?
What gate(s) do the TK flights typically depart from? FlightAware, etc. only shows they depart from Terminal N, but never lists the gate.

I have limited success talking with THY on the phone and unfortunately their Atlanta office is closed today.

A little help would be appreciated.

p.s. What lounge do THY business passengers use.
