Flooding, Philippines

As an archipelago, inter-island travel via watercraft is often necessary. The busiest seaports are Manila, Cebu, Iloilo, Davao, Cagayan de Oro, and Zamboanga. Passenger ships and other sea vessels such as those operated by Superferry, Negros Navigation, and Sulpicio Lines serve Manila, with links to various cities and towns. In 2003, the 919-kilometer (571-mile) Strong Republic Nautical Highway (SRNH), an integrated set of highway segments and ferry routes covering 17 cities was established.
Some rivers that pass through metropolitan areas, such as the Pasig River and Marikina River, have air-conditioned commuter ferries. The Pasig River Ferry Service has numerous stops in Manila, Makati City, Mandaluyong City, Pasig City, and Marikina City. There are 3,219 kilometers (2,000 miles) of navigable inland waterways.
There are 85 public airports in the country, and around 111 more that are private. The Ninoy Aquino International Airport (NAIA) is the main international airport. Other important airports include the Diosdado Macapagal International Airport, Mactan-Cebu International Airport, Francisco Bangoy International Airport and Zamboanga International Airport. Philippine Airlines, Asia's oldest commercial airline still operating under its original name, and Cebu Pacific, the leading low-cost airline, are the major airlines serving most domestic and international destinations.
