Never again.
Before I booked my round trip ticket from LAX to Europe, with one stop in Germany, final destination Denmark, I called them and asked if I could get off in Germany and not take my last flight to Denmark. They said sure, no problem. But it turns out that that would be considered a "no show" and I would use my return flight. So I've been calling them a lot. And still waiting for their "investigation". Lol. They said it will take 24-48 hours. It's been three days.
