I booked two business class seats in September 2021 for travel in June 2022 - Sydney to London return. In April 2022 JAL informed me that two of the legs were now cancelled. They offered no alternative for one of the legs and the other leg they offered a connecting flight 17 days after the first leg. Go figure. In the end I had to cancel my flights and rebook with another airline at greater cost. I will never use JAL again. Having spoken to others it appears this is common practice with JAL. Beware. What was once a premium airline is no more.
