Sainðaul Asunahama International Airport (安作崎空島國際空港 - Saindzaul Asunahama Kukujai Kūnkō) (WAAT: SUL, ANACA: DZSL) is the main international hub of Izaland, main hub for Izaland Airlines and Uletha Eastern Airways, serving all major international destinations worldwide.


The "Asunatotsu" bridge connecting the airport island with the mainland

The airport opened in 2014 on a 9 sq km artificial island offshore Kubori island to relieve the congestion of the former Sainðaul Tswankanami Airport, now reduced in size and used as a military base, and the Sainðaul Kanui Airport, located in the continental area of the city, now serving mainly domestic and short haul destinations.

Construction works

The genesis of this airport backs to year 1998, when the former international airport of Izaland, Sainðaul Tswankanami Airport started to show signs of saturation. Different projects were made about the location for a new international airport, including the expansion of the main domestic terminal of Kanui Airport. However, the promising growth of international flights pushed for a wider projects, so the idea of creating a wide airport on an international island took over.

At first, there were different ideas for the location of the new airport, including near Kawayatsu or Sabullan. However, the Ministry of Infrastructure, asked, in 2001, to locate the new airport possibly along the route of the newly to be built high speed railway (the Sainðaul - Warohan Saikai Line), so an area in Komokata Prefecture, about 2,4 km offshore between Riimibaiken and Chikawari was chosen, due to the low depth of the sea (not more than 35 m in the deepest area). Particular attention was made to avoid endangering the reef located in the area.

The preliminary project was ready by september 2005, and the complete financing of the airport, including the undersea high speed railway, was done by spring 2007. Building works started finally in 2008, first by landfilling the area to create the island. At the same time, tunnel boring machines started digging the two single tracked 18,7 km tunnels from Komokata to Chikawari area, and the HSR station was nearly completed by 2012. The last two years were taken to complete the construction of the airport terminal itself.

In 2017, due to the increasing low cost flights, especially by the growing IzaFly low cost carrier, a new terminal was built on the southern area of Asunahama island. The terminal behaves actually as a satellite building, as everyone needs to pass through the check in and immigrations of the main building. The transfer to the low cost terminal is guaranteed by a inter-terminal people mover.


View of the inside of the airport

Since the landfilling of the airport island has been one of the biggest project in Izaland, at an estimated cost of about 18 billion USD, a symbolic name was chosen fo the island, calling it Asunahama (空島, asunahama), meaning "sky island". This name was also chosen to call the airport itself.

Airlines and destinations


Sainðaul Asunahama International Airport, as the name suggests, is mainly intended for international flights use. Due to the limited extension of Izaland, domestic travel is mainly satisfied by high speed rail (whose trains also stop in the underground passing station), allowing code-shared trains to reach the center of Sainðaul and all the major cities in Kubori island.

A limited number of domestic flights, usually one in the morning and one in the evening however are available from Sainðaul Asunahama International Airport to a selected number of domestic destinations to allow a smoother transit according to the peak departures/arrivals of intercontinental flights.

Here is the list of the flights:

  • To/from Warohan (WRH): 2 am flights and 2 pm flights (each by IZ and UE, for a total of 8 flights per day)
  • To/from Daishin (DAI): 1 am and 1 pm flights (each by IZ and UE, for a total of 4 flights per day)
  • To/from Isadashi (ISA): 1 am and 1 pm flights (by IZ, 2 flights per day)
  • To/from Sagoma (SAG): 1 am and 1 pm flights (by IZ, 2 flights per day)
  • To/from Gaintei (GTN): 1 am and 1 pm flights (by IZ, 2 flights per day)
  • To/from Kikknās (KIK): 1 am and 1 pm flights (by UE, 2 flights per day)
  • To/from Kanlisahna (KLS): 1 am and 1 pm flights (by UE, 2 flights per day)

Domestic transit with the SATMEX

To transit to the farthest national destinations, or those located on islands, usually passenger need to move to Sainðaul Kanui Airport, located south-east the continental side of the city. To allow this transit they can use for free (as its price is included in the air ticket fare) the SATMEX shuttle, a train running on the high-speed line skipping all the stations in the middle, even Sainðaul central station, that reaches Kanui Airport in 35 minutes. Passenger's baggage is also transferred by the airport into the train's baggage wagon, so they do not need to worry about anything. However, immigration process (when entering Izaland or exiting Izaland) must be completed at Sainðaul Asunahama International Airport. The minimum connecting time using SATMEX is 120 minutes.


Sainðaul Asunahama International Airport is the main hub in Izaland for Izaland Airlines (IZ) and Uletha Eastern Airways (UE), offering a good hub and spoke solution for international aviation. The airport is also hub for the low cost carrier IzaFly, flying from the Low Cost terminal, opened in 2017 on the southern area of the airport.
