Do you have a Spirit Airlines flight? The spirit airlines detroit terminal was easy for me to navigate recently. Employees were kind, and check-in kiosks expedited the process. While you wait, there is enough sitting and a few nice places to grab a bite. To be honest, this terminal is among the best I've encountered if you're flying Spirit. It's quick, clean, and does the job well, but don't expect glamour. The spirit airlines detroit terminal was easy for me to navigate recently.
