I did toy with doing this once. The travel department where I worked were kicking up a fuss about me flying LHR-xxx direct while I was on 100% travel there, as they got kickbacks from KLM, and so wanted me to fly LHR-AMS-xxx, despite the fact that this now meant a 6am flight on a Monday, returning at 8pm on a Friday (and I live about 2h from LHR).

On the outbound, there was a 40-minute connection (non-Schengen to Schengen), so the possibility for misconnections was definitely there, and my inbound from LHR was 10 minutes late arriving. I could so easily have been "delayed" going through immigration etc and turned up several hours late to make the point that the indirect flight was an inconvenience to us all.

But I just couldn't bring myself to do it.

That was an awful travel department. The agents were shocking - for long-haul J flights, I'd often get a quote of 3x what I knew I could get. I used to end up dictating the fare basis to them over the phone!
