I didn’t know “skiplagging” was a thing, but I actually did it once myself and almost got in trouble for it. 1. I booked roundtrip A → B → C and C → B → A. 2.

I didn’t know “skiplagging” was a thing, but I actually did it once myself and almost got in trouble for it. 1. I booked roundtrip A → B → C and C → B → A. 2. I skipped B → C because I needed to spend a few days at B. 3. I booked a separate one-way B → C which was cheap because it was a short hop. What I didn’t realize was that the airline canceled my C → B → A return trip when I skipped B → C. Fortunately, I discovered this early when I spoke to customer service about an unrelated question: the airline kindly explained to me what happened, warned me not to do it again, and rebooked my flight back.
