copyright DTW Terminal is based out of Detroit Metropolitan Airport North Terminal (Terminal N) (DTW). Convenient features at the terminal include self-check-in kiosks, food options, and retail stores. With additional costs for things like baggage, seat preference, and in-flight amenities, Spirit's low-cost business strategy offers flights that are affordable. https://www.globalterminalsdesk.com/spirit-airlines/spirit-airlines-dtw-terminal-detroit-metropolitan-wayne-county-airport/
