Looks like MH has cancelled / blocked out MH70 (10:15am) flights to NRT and MH71 back.
I am on MH88 (~11:30pm) in ~20 days, looks like I’m still fine.
However, I did see this at the top of my booking… though my separately-ticketed flight back which is just a bit more than 30 days away does not show anything yet.
I am not changing anything (though maybe will shift to the JAL flight if no charge on the way back), but interesting to see for a non-affected flight; I expect the difference in date would still apply, just not the change fee.
