“Skiplagging” — or booking a flight with a layover to skip the last leg of travel — is a common hack for travelers who don’t want to pay for a direct flight or who to save money on airfare to a connecting destination. Airlines contend the practice results in lost revenue for seats on planes.
To be clear it’s not illegal for the passenger to do this. Airlines just hate it because it breaks their business model in a way that lets someone else make money.
I was hoping the silly “you rascal” made the sarcasm obvious.
