The Frontier Airlines San Juan office provides a convenient and efficient customer service experience. Staff are generally friendly and attentive, assisting with ticketing, baggage, and flight inquiries. While the office can get busy, the team manages the flow of customers well. However, the office itself is relatively small and basic, with limited amenities. Overall, it’s a solid option for resolving any flight-related issues, but expect minimal frills. Good service, but not luxurious.
