You guys shouldn’t have been wanting to travel in the first place because of COVID.

Is it unsafe to travel during the pandemic, yes, but alot of places don't actively has measurements that strictly forbid traveling. There are group limits and other restrictions, but people should be free to travel without having someone jump down their throats about it. If they're adults and know the risk let them be it's their life, not yours.

While I sympathize with the desire to travel (and see family and loved ones) this season, that is exactly the wrong thing to do now! There is a flare up in COVID-19 and the risks of getting or spreading the disease is too high to be traveling or getting together with people you are not with at home. About half the people who get it don’t show symptoms but they can spread the germs to people who will get sick.

what happened to STAY THE FUCK HOME?

Seriously people. What part of pandemic do you not understand? This is one of the reasons the pandemic is out of control. We all need to make sacrifices and stay home!!! More than 300 thousand people have died!

Better to lose one Christmas than all of them.

This sounds like OP is Aussie, pretty much the whole of Aus is Covid free except for this new outbreak in Sydney (the only red zone in Aus). So it sounds like OP's frustration is because out of anywhere in Aus for an outbreak to happen, it was the one place OP was planning to go.

We're in a pandemic. Deal with it.

You absolutely deserved your trip getting cancelled during g this pandemic. How selfish of you. Stay home!
