I got a pair of those too back in Jan for quick week in HKG in November. Now Hong Kong is requiring 14 days quarantine (not easy when you're there 6 days). The fare was so crazy cheap, that anything that mentions repricing will probably cost the same amount on top.

I've been looking at that One Free Rebooking and I'd be happy enough to postpone for a year and push it back till Nov 2021. Anyone know if they're accepting bookings that far in advance?

That rebooking offer says it's only till the end of August... is that the latest I can wait?

One last question. looking on ITA Matrix and Google flights, I can no longer find the exact same flight times. Can't I cancel for a refund (though I'd hate to miss that great value) when they inevitably have to email me to say there's been a change in schedule?

cheers,
