At Orlando International Airport (MCO), Frontier Airlines MCO Terminal uses Terminal A for its operations. Travelers will find check-in counters on Level 3, where staff assist with boarding passes and baggage. Terminal A is modern and includes access to shops, food options, and comfortable waiting areas. The layout is clear and passenger flow is smooth. It’s recommended that Frontier passengers arrive at least 2 hours before their scheduled flight to allow enough time for airport procedures, especially during high-traffic periods like holidays or weekends. https://www.airportsterminalslocation.com/frontier-airlines/frontier-airlines-mco-terminal-orlando-international-airport/
