Whats up with Jetstar ?
They knew they were out to make trouble. All 10 had 'exemptions' so police were powerless. As was the ability of staff to boot them off as a breach of terms of ticketing.
Because noone took control of the exemption process. Others abuse it to their gain
And one wonders why legitimate users get abused.
I would take a guess and say I've had anti maskers (where I've actually seen them) on probably at least 20 of my flights this year. Even in recent months when I've been to Auckland in L3 and L4 there have been the odd one on flights.
Exemptions are perfectly legal - including the downloadable print at home ones. We know the Govt and MoH have truly made truly dumb decisions this pandemic, and mask exemptions sit right near the top of that list.
I even had one sitting next to me a few months ago and was powerless to do anything. If I'd complained Air NZ would have just made me move.
