Just got an email from JL regarding this. They even offered compensation, and I didn't even ask for it.
Funny that they are offering either Amazon gift cards or JMB miles. So no JAL Coupon this time? And it's a much more generous offer/mile to cash conversion rate compared to the IFE malfunction. Last time was either JPY3,000 JAL Coupon or 3,000 miles. This time it's 5,000 miles or $50 Amazon gift card. Not sure if my amount is higher than others because of them tripling charging me for transpacific business class. Others only have been double charged
