รอบรั้วมหาวิทยาลัยราชภัฏลำปาง

Hey everyone!
I'm flying for the first time with Southwest Airlines from Atlanta Airport, and I'm a bit confused about which terminal they operate from. I read online that it's Terminal North (Concourse C), but I wanted to double-check with those who've flown recently.

Can anyone confirm if that's still correct? Also, how's the overall experience at the Southwest Airlines Atlanta Airport Terminal? How early should I reach? Are there any good food options or lounges nearby?

Would appreciate any tips or suggestions from frequent flyers. Thanks in advance!
