Lufthansa, a major German airline, is now locked in a testy legal battle against a single, solitary passenger over a deliberately missed flight.
The Lufthansa passenger paid 657 euros ($741, at today's rate) to fly business class from Oslo to Seattle and back, with layovers in Frankfurt.
The airline is seeking payment from the unnamed traveller, who it believes booked the ticket as part of a widely used hack of buying cheaper flights by avoiding the premiums placed on non-stop options.
It can be a sneaky way to save money on fares, with direct flights sometimes costing more than stopover journeys.
For example, someone flying from New York City to San Francisco could book a cheaper flight from New York City to Lake Tahoe with a layover in San Francisco - then simply get off there.
And now you might also get sued. Airline officials, however, would like to take it one step further by outlawing it completely.
The principle that airlines charge less for more flights, lies behind pricing strategies by "network carriers" such as Lufthansa, Air France and British Airways.

Skiplagging can cause delays for airlines as they wait for unaccounted-for passengers, with carriers that have flights routed through hub airports - such as Lufthansa in Frankfurt and Munich - particularly affected. He successfully completed all legs of the departing flight, but on the return leg left the plane in Frankfurt.
The defendant asked the court to dismiss the airline's request, saying the airline's terms and conditions don't apply to his actions - and that Lufthansa's request to recalculate the fare was incomprehensible.
In December, a court in Berlin threw the case out.
Lufthansa lost the initial court case, but is appealing the decision.
German airline Lufthansa is trying to sue a passenger it says wilfully booked a cheaper ticket with no intention of making the final leg of their journey, it is claimed.
The more you bloody know.
