Japan Airlines has reached its first codeshare agreement with soon-to-be oneworld alliance member Air Berlin.

Flights between Frankfurt and Berlin operated six times a week by Air Berlin (which styles itself ‘airberlin’) will be coded with JAL’s ‘JL’ flight designator from February 12, subject to the two carriers reaching government approvals. Codeshare tickets are now available for sale.

Air Berlin, which is due to join the oneworld alliance on March 20, is Germany’s second-largest airline and has an extensive domestic and international network. It carried more than 35 million passengers in 2011.

Japan Airlines' fleet includes 36 Boeing 777s, among them six Boeing 777-300s and 14 777-300ERs

With an average aircraft age of five years, Air Berlin’s 170-aircraft fleet is one of the most modern in Europe.

The new codeshare agreement adds another connection option for Japan Airlines customers traveling to Germany’s capital city. On top of the current connection on British Airways from JAL’s daily flights to London, customers can soon also reach Berlin via Frankfurt.

JAL operates daily to Frankfurt from Tokyo with a Boeing 777-300ER fitted with JAL First Class Skysleeper Solo, Executive Class Shell Flat Seat and Premium Economy service.

At present, JAL customers can transit in Frankfurt to Helsinki and Madrid, on fellow oneworld member airlines Finnair and Iberia respectively.

Among the aircraft in Air Berlin's large fleet are 15 Airbus A321-200s, in service or on order. Air Berlin is unusual in operating large numbers of A320-family jets and Boeing 737NG-family aircraft. The carrier also operates Bombardier Q400 turboprops, A330-200 and A330-300 widebodies and has 18 Boeing 787-8s on order

Japan Airlines’ new codeshare flights from February 12 include JL7863/AB6564, operating on business weekdays from Frankfurt to Berlin. The flight, which may be operated by Air Berlin partner regional carrier LGW, is timed to depart Frankfurt Airport (FRA) at 6:55 p.m. and to reach Berlin (which in June will have the new Berlin Brandenburg Airport, IATA code BER) at 8:05 p.m. Until June, the flight will arrive at Berlin-Tegel Airport (TXL), which that month will be closed.

On Sundays, the same codeshare flight is scheduled to depart FRA at 7:20 p.m. and land (for the next few months) at TXL at 8:30 p.m. From June the flight will move to Berlin Brandenburg Airport.

In the other direction, flight JL7862/AB6563 leaves TXL/BER at 4:55 p.m. and lands at FRA at 6:10 p.m. on business weekdays. On Sundays, the flight becomes designated JL7862/ AB6565 and departs TXL/BER at 5:40 p.m., arriving at FRA at 6:55 p.m.

Japan Airlines’ connecting outbound daily flight JL407 from Tokyo’s Narita International Airport (NRT) to Frankfurt leaves NRT at 12:25 p.m. and touches down at FRA at 4:40 p.m. the same day, local time.

In the other direction, JAL’s connecting daily flight JL408 pushes back from the gate at FRA at 8:25 p.m. and gets to NRT at 3:55 p.m. the following day, local time.
