How the great have fallen
The only way to upgrade a ticket is to bid on a ticket. The only way to do this is via their website. It is not guaranteed you’ll get an upgrade and you don’t find out until 24 hrs prior your flight. According to their website you can not talk to an advisor about upgrading. I wanted to upgrade my very elderly mother’s ticket from Japan so she would be comfortable on her flight home after falling ill abroad. There is also no useful information on their website on how I could get her airport assistance for her. JAL once was one of the best most highly rated airlines. What has happened?
