therefore you do regard the therm 'freight' as inferior to 'passenger'? You seem biased.
Payload is payload, and whether or not you call the load device a seat or a pallet, it is still there to ensure the safe transportaion of the payload. Added bonus of what is referred to as passenger is that contrary to freight they usually are able to load and offload themselves.
The airlines are offering a transportation service between two points on the planet. That is all. The rest is 'product enhancement'.
The most agressive and quite sucessful air carrier of the time is called Ryanair, you may have heard of them. They definitely do not have a reputation for excellent passenger handling skills.
