- My interaction with Frontier Airlines MCO Terminal was quick and easy. Passengers were assisted by self-service kiosks and friendly workers during the easy check-in process. Although a little long, the security lines moved steadily. There were plenty of dining and shopping options in the tidy terminal. The flight left on schedule, and boarding was well-organized. Although the seats were simple and had little legroom, the plane was clean. The crew was polite and professional. All things considered, it was an inexpensive, straightforward trip that was perfect for anyone searching for a quick and economical trip.
