JAPAN's Sendai Airport has reopened to commercial flights, the last airport to do so in the country's tsunami and earthquake-stricken northeastern region.

Japan Airlines (JAL) and All Nippon Airways offer six daily return flights, four from Haneda Airport and two from Itami Airport in Osaka, reported Newark's Journal of Commerce. The airlines have yet to decide on flight plans after the projected April 21 normalisation date.

Some 2.8 million passengers transited the airport in the 12 months to March of last year. A JAL flight landed with about 120 passengers from Haneda Airport in Tokyo on Wednesday, the first commercial flight since the devastating March 11 earthquake and tsunami. Until then, the airport was only open to military aircraft with relief supplies.
