That is very good advice for all of us.
For anyone reading who’s wondering what a low cost index fund looks like, make sure you’re choosing one that’s charging under 1% per annum in fees and has a history of good performance. Under 0.6% in fees is ideal.
Don’t worry Roz, I only have a relatively small amount invested in airlines that is far outweighed by my investments in far safer ETF’s. If the airline goes under, I won’t lose more than I was comfortable gambling in the first place.
I don’t recommend anyone do what I’ve been doing in this experiment.
