Common Complaints

Limited Recent Commercial Passenger Feedback: A notable absence of recent, detailed commercial passenger reviews makes it challenging to gauge current sentiment beyond wait times.
Lack of Courtesy Shuttle (Historical): Older reviews indicated a lack of a courtesy shuttle to local restaurants during weekdays, requiring travelers to take a cab. While FBOs may offer courtesy cars, this might not apply to all commercial passengers.
General Aviation Costs (Historical): Some older general aviation reviews mention a ramp fee and "salty" fuel prices.

Overall, The Florida Keys Marathon Airport (KMTH/MTH) appears to offer a generally positive and efficient experience, particularly for private and general aviation, and benefits from relatively short security and immigration wait times for all travelers. The presence of on-site customs is a significant advantage for international arrivals. Travelers should plan for ground transportation as specific courtesy shuttles may be limited.
