$39 Flights
In 2006, the airline Alitalia offered $39 flights from Toronto to Cyprus, at least, that’s what customers assumed. But it turns out that the cost was a typo. The airline wanted to offer the flights at a cost of $3,900, not $39.
Regardless, two-thousand tickets were sold at the extremely low cost before the airline realized they had made a mistake and corrected it. But at that point, there was no way they could deny the people who had bought the tickets for their flight. So, they allowed them to board their flights, but the mistake set Alitalia Airlines back millions.
