I've never intentionally skiplagged, but there was one time the first leg of my journey was late, I missed my connection and I was going to be in the airport for 8 or 10 hours to catch my 1 hour flight to my final destination. I decided not to, and instead minimized my misery and bought a ticket for the 3.5 hour train ride home.
If an airline looked at that behavior and blacklisted me for not using the service I paid for, then they are the greedy fucking bastards.
