Japan Airlines (JAL) will be retrofitting nine of its Boeing 767-300ER aircraft starting October.
This comes after the airline announced last year that it will be revamping its 767s and Boeing 777-300ERs with a new cabin product.
In the latest round of revamp, the 767s, which are deployed on international services, will be retrofitted with 24 business and 175 economy class seats, says the Oneworld alliance member.
JAL's spokesman was unable to confirm when the retrofit programme will be completed.
The retrofitted aircraft will be deployed on the Tokyo Narita-Vancouver route starting December 2013, before being used on flights to Honolulu and selected destinations in Southeast Asia by fiscal year 2014.
The aircraft's business class, with a 1-2-1 configuration, will have seats with unimpeded access to the aisle. These seats, supplied by Zodiac Seats UK, a division of Zodiac Aerospace, will also feature a flexible side table, exclusive storage space and larger 15.4in (39.1cm) touch panel TV screens.
The economy class seats from Zim Flugsitz, with a 2-3-2 configuration, will feature a seat pitch of up to 86cm, up from the existing 79cm, and a slimmer seatback, which will allow a maximum of 10cm more legroom. These seats will also have 10.6in touch panel TV screens.
Individual seats in both classes will be equipped with a USB port and a universal AC power outlet.
As of 31 May, JAL has completed retrofitting four of its 13 777-300ERs. These aircraft are deployed on services to New York and London, says the spokesman.
