Unsurprisingly, Carnival (NYSE: CCL) was decimated when the coronavirus pandemic brought travel to a complete halt, and the business is still trying to fight its way back to where it was a few years ago. Luckily for shareholders, Carnival's recent progress is a sign of hope. In the most recent fiscal quarter (Q1 2023, ended Feb. 28), Carnival generated revenue of $4.4 billion, up 175% year over year.
