Domestic flight booked on JL website, cannot register OW number
I booked a couple of domestic flights on JL website and paid for them. However, I have been unable to register my OW (BA to be specific) membership number despite trying a few times for the last couple of days.
In fact, I cannot even get the JL MMB to pull up the booking now (even though it let me do so yesterday). I tried three different browsers, and I tried both their English and Japanese sites, but it just says "A system error occurred. We apologize for any inconvenience. Please try again later."
Is anyone else having a similar issue, or is it just me?
