Anyone successfully gotten their credits? They keep on closing my case.

You need to push Expedia to get back to your regarding the cancelation/refund/rebooking since they are the one who do the booking on behalf of you.

That why I always advocate booking direct with the airlines instead of OTA/Physical Travel Agent as if there any issue Airlines will taichi it to the people who does the booking for you.

And they like to put additional terms that required pax to go to agent should they have any waiver in place like current situation.
I think October is still considered okay as opposed to September.  End of day is depending on pure luck

Went twice for work on Sept on two different year and it was day and night difference not fun being landed into Narita and stuck overnight in airport right after Typhoon which was supposed to be strongest at the time before it was superseded by Typhoon Hagibis in Oct

Ah i see, I supposed you booked under Expedia bundle kan? Yes, some of the deal was quite tempting. But decide not to do so since worry when shit hit the fan (eg during typhoon) and what not. If these does not happen then I say it is good deal.

Even my booking via company appointed travel agent also headache when this happen. Airline will just say "please refer to the travel agent" 

Once i asked my buddy in airline also cannot directly touch my booking as it will trigger auto chargeback to the agent who does the booking it need the agent itself to move things around.
