You didn't say what the post from 2017 concluded? Why do you think things might have changed?

My experience is from 2014-2019, so maybe too old for you. But I traveled on Virgin domestically with a Pelican EL30 case for business at least a dozen times, and Qantas a handful of times. It is a 155 cm linear case, and it looks very big. I never had any question or issue with it.

My research at the time showed that if it is oversize, it can be subject to special handling fees, but as long as it isn't overweight there isn't a set fee for oversize luggage. So it's kind of up to the agent... but there is no blanket prohibition on oversize baggage, it just gives them the ability to charge fees if they deem necessary. From what I can see, the rules are still the same.

So IMO I wouldn't worry about your bags, as long as you are prepared to pay fees if they decide so at check-in.
