Hello. I can assist you with your question.
Actually, Delta has just remodeled their check in terminal there and it's all very convenient
The check-in of your one free/person will be the same as the good old days when we didn't have to pay for luggage at all.
You don't have to do anything, but check it in when you get there.
You are allowed one carry-on as well.
So, for curbside check-in:
STEP 1. When you pull up to the curb, present your photo ID along with your confirmation number, destination, flight number, or eTicket number to one of our Skycaps.
STEP 2. Hand your checked bags to the Skycap, grab your boarding pass, and head straight to security. It's that easy.
There is no fee for using curbside check-in at the airport, but gratuities are always appreciated for outstanding service.
Delta has curbside checking at both their North and South Terminals at Hardsfield.
