Charging travelers more money for the same stuff is working extremely well for Carnival Cruise

Carnival Corp. reported record-breaking earnings on Tuesday, in large part because customers are willing to pay more for tickets and on-board expenses. The cruise-liner brought in $5.8 billion in revenues and $560 million in operating profits in Q2, nearly five times more than in the same period last year.

The company expects that success to sail into 2025: Reservations for cruises next year are even higher than they were a year ago.
