Malaysia Airlines will begin codesharing on three of fellow Oneworld alliance carrier Cathay Pacific’s trans-Pacific flights to the US starting later this week as part of an expansion of the two carriers’ codeshare partnership.

From Sunday, March 25 onwards the carrier will place its MH code on flights operated by Hong Kong’s flag carrier between Hong Kong and Los Angeles, New York (JFK) and San Francisco.

The codeshare will enable travellers flying with Malaysia Airlines to reserve seats through Hong Kong to the three US destinations as part of a single booking.

Malaysia Airlines currently flies two aircraft on its thrice-daily service between Kuala Lumpur and Hong Kong – its Boeing 737-800 and its newer Airbus A330-300.

Business Traveller reviewed the airline’s B737-800 business class on this route in 2017.

Cathay Pacific meanwhile flies three times a day to Los Angeles, four times a day to New York (JFK) and 20 times a week to San Francisco, using a combination of its B777-300ER and A350-900 aircraft.

The Hong Kong carrier also plans to launch its longest non-stop route in its network this September, to Washington DC, using its first A350-1000.;
