I booked a business-class non-stop ticket one-way from AKL-LAX (non-stop) on Air Canada (codeshare, actually Air New Zealand) for a ridiculously good rate for this December. I chose to do so because it was thousands of dollars cheaper than the alternative, and of the OTAs showing the approximate price, at least Vayama was owned by Trip.com (read: not going belly up).
Unfortunately, I now find myself holding my breath. I cancelled my miles flight there, but Air New Zealand isn't cancelling the AKL-LAX flights at all despite an entry ban, so I'm going to have to get an Air Canada voucher at some point, or pony up the $400 cancellation fee to Vayama + Air Canada. Not sure which will be less painful. (Or if either will be possible.) My best hope is that Air Canada will let me turn it into a voucher directly without going through Vayama.
I also noticed that Vayama has stopped showing international tickets. What does that portend?
