All Nippon Airways (ANA) is effectively only operating one of its Boeing 747-400s on international routes because the other two are auxiliary aircraft.
"We have three 747-400s for international flights" but "the other two are auxiliary aircraft and are usually not used on routes," says an ANA spokeswoman.
She says ANA plans to phase out one by the end of March 2011 and the other two will go by the end of March 2012.
ANA uses its 747 international aircraft on the Tokyo Narita-Paris Charles De Gaulle route, says the spokeswoman, adding that it is replacing the 747-400s with Boeing 777s.
According to Flightglobal's ACAS database ANA's three 747-400s were built between 1991 and 1993.
It also has 10 Boeing 747-400Ds, a special derivative that Boeing developed for Japanese carriers needing to transport large numbers of people on busy Japanese trunk routes.
