Hello! My last Sun Country BNA Terminal » was a generally pleasant experience. The terminal was tidy, and checking in was easy. TSA lines weren't terrible, but they do get long, so come early just in case. The waiting area was roomy but had few food options. Boarding was prompt, and the staff were professional. I do wish the terminal had more charging stations, but it wasn’t a dealbreaker. If you’re flying Sun Country from Nashville, it’s a decent experience!
