Using your logic than the following would also be considered setaling:
- Flying to a nearby town beacause it's cheaper
- Flying on a different day/time than what is intended because it's cheaper
- Flying one airlines half-way, than continue on different airlines (nested ticketing) because it's cheaper.
All of the above constitutes loss of income to the airlines, due to the passengers lying about their true O/D.

Am I stealing if I choose to fly DL to SIN even though my true destination is CGK? ( I could book an itinerary to CGK on delta.com at a much higher price, so i chose to fly SIN-CGK on an LCC) I did misrepresent my O/D to Delta. Is it also illegal?
