we do a good job, the airlines don't want to pay for the arms race they create by making their rules around pricing so difficult that no single person in their business understands it (personal opinion). I believe airlines that do use our services do much better than the ones that don't (like +0.5-1% more margin). Think about how much money that is to someone like united with 38 billion in revenue.

The only reason I have a job is because the reservation system is old and has all sorts of scope creep to do things that aren't really airline related but were implemented to make a sale.

tl;dr I agree with the guy at the end of the story.

YQ : fuel surcharge (which is apparently not related to fuel costs)

3X : method to eliminate this additional cost by adding an extra leg to the trip (which is then not taken).

Could you tell us some more about how you do it?

Experienced dumpers scorn novices seeking guidance, unless the newcomers can offer hot new 3Xs in exchange.
