Such people should pay more for their tickets. How come I pay for excess
baggage when this guy weighs more than my baggage and me put together?

They're talking about that in America. We're, um, bigger.

How come we can pay significantly more for a 300-mile trip between two
small
markets than for a 3000-mile trip in a competitive city pair?

I've heard that it's actually illegal and goes back to a law passed because
of a similar rate metric used by the railroad in the old days to gouge
ranchers in Texas. (It cost far more to go between two hops than it did to
go from one end of the line to the other.)

Apparently it was an issue here in Oregon many years back due to commuter
rates to rural areas being more expensive than service to SFO, SEA, etc.
Never heard how it resolved.
