Hidden-city ticketing

Booking a ticket through your real destination to a cheaper final city, then walking away at the connection — buying A–B–C because it undercuts A–B. It works only with carry-on luggage, only on the last segment, and it breaches the fare contract: airlines cancel remaining segments, and repeat use risks frequent-flyer account action. We neither sell nor recommend it; we list it because buyers should understand the tactic and its real costs before an engine tempts them with it.
