Hello! At my interaction with Frontier Airlines MCO Terminal was surprisingly easy. Their kiosks made the check-in procedure quick, and the staff was kind and understanding. Signage made navigation simple, and security proceeded swiftly. There was enough of seating close to the gates in the tidy terminal. There weren't many food options, but they were good for a quick snack. Everything was quite structured, and boarding proceeded in groups. Just be ready for additional charges from Frontier. Overall, a respectable experience flying with a low-cost airline at a large airport. Particularly for quick travels, I would take them from once more.
