Here’s an interesting little histogram to illustrate how Covid (thanks, China!) killed the airlines, but they have managed to crawl their way back.
I would mention, however, airlines have never been a good investment. Take United Airlines (please!) If you had the good sense to invest your cash into it 17 years ago, you would be looking at basically a 0% profit right now. So let’s all agree that not every stock is freakin’ AAPL or NVDA. A lot of stocks just plain suck, even over the long haul.
You can always test this theory over on Slope’s “Woulda Shoulda Coulda” page, which is also great for financial self-flagellation.
