Apparently there's an issue on JAL website and JAL is posting charges from the same ticket purchase multiple times. JAL agent claims they have fixed the problem but then also told me they are still investigating my multiple charges and cannot guarantee they won't post for the 4th time. So if you have purchased a ticket from JAL website recently, check your credit card statement/account.

Below is the timeline
4/24 Purchased ticket via JAL website
4/28 Credit card account shows 2 posted charges from JAL with the same amount. Transaction date is 4/24
4/28 Called credit card and JAL. JAL said they will get back to me, most likely on Monday 4/30
4/30 No call from JAL
5/3 JAL charged me for the THIRD time for the same ticket but this time the transaction date is 4/26. Called JAL and they are still investigating and requested for more info from me (they could have called me after I filed the first complaint)
