Kos, Greece is served by two airports, Kos International Airport (KGS) and Kalymnos Island National Airport (JKL).
Kos International Airport (KGS) is the main airport on the island, offering a wide range of flights from various prestigious airlines. It benefits from its convenient location, just 24 km from the popular tourist resorts of Kos town and Kardamena. Travelers departing from KGS can expect a short travel time and reasonable transportation costs to reach the airport, making it a hassle-free journey.
On the downside, Kos International Airport (KGS) can get quite crowded during peak travel seasons, resulting in longer queues and waiting times. However, the airport management has made efforts to improve the facilities and waiting areas to accommodate the increasing number of passengers.

Located on the nearby Kalymnos Island, this smaller airport provides a charming and less crowded atmosphere. Travelers departing from JKL can enjoy the tranquility and simplicity of a smaller airport, avoiding the hustle and bustle often associated with larger airports.
However, it is important to note that reaching Kalymnos Island National Airport (JKL) may require additional costs and time. Travelers would need to take a ferry or a domestic flight from Kos to Kalymnos Island, followed by ground transportation to the airport. This could be an enchanting journey for those looking to explore more of the Greek islands, but it might not be the most time-efficient option for those with limited travel time.
In conclusion, both Kos International Airport (KGS) and Kalymnos Island National Airport (JKL) offer their own benefits and downsides for travelers departing from Kos. Consider the convenience and prestige of airlines at KGS, while the peaceful ambiance of JKL may appeal to those seeking a unique travel experience.
