Go to Continental.com - select LAX-AKL non-stop only, reward search
All of January and February is unavailable (summer), but then in March, coach is available daily!
(confirmed by KVS)
Go to Aeroplan.com - select a random day in March 2012 - NOTHING...
weird... but I am inclined to think its a glitch rather than blocking coach - what would be the point of that? - making people fly AC YVR-SYD and collecting $500 fuel surcharge?
AKL-SYD - same story for Aeroplan - it just looks like no NZ is available period. Serious glitch or serious blocking? Let us speculate
