Okay the sky isn't falling ... but it looks like NH is decreasing the frequency of their direct RGN-NRT flight. They offered me the same flight, but 3 days before. I probably can't do that (I haven't booked up the leave at work!), asked about in the days after but availability was a bit poor as it is Easter weekend.
Will discuss with the Mr. But we might be spending more time in Myanmar
(bought flights to there, but not from Canada yet, so no skin off our noses).
Edit: just had the couple hours stopover in SEA, so none of the DOT 24hr thing would apply.
