[Update: JAL and PG have issued a press release regarding this new JMB partnership and codeshare agreement] 

Japan Airlines (JAL) announces the new partnership with Bangkok Airways (PG). JAL Mileage Bank (JMB) members can now redeem miles on PG operated flights. But there are no words on mileage accumulation rate yet you will NOT be able to accrue mileage on PG flights. To celebrate the commemoration of the new partnership, JAL is launching a discount mileage campaign which JMB members can redeem a economy class roundtrip ticket on PG with as little as 5,000 miles!
