Now that the price of crude oil is negative $38 per barrel, Airlines are a perfect investment opportunity (this is a joke).
Airlines should get paid by the sellers to take jet fuel, and fly around the world empty with no passengers. This way, they can keep the costs very low since there would be no need to give passengers any meals. Also, the flight attendants would not be needed.
This would make airlines profitable again and take care of the oil storage problem.
Now that I think about it, Uber could do the same.
Disclosures: I would never buy an airline stock even if the economy was doing well. Sorry, I just could not help myself. I had to write it.
