Помогите, пожалуйста с терминами! avia.

[Twinkle7]

Затрудняюсь адекватно перевести некоторые термины, применительно к отрасли авиаперевозок:
1) traffic mix - the proportion of traffic travelling at each different price on offer within the given fare structure in each market.
2)Output. The output produced by an airline is measured by multiplying a unit of seating or payload capacity by distance flown.
3) Capacity. 'Capacity' is a fleet's potential output if fully utilised, and 'output' as the ASMs (available seat-miles) or ASKs (available seat-kilometres) and ATMs (available ton-miles) or ATKs (available tonne-kilometres) actually supplied to the market.
4) Overcapacity. This arises when aircraft are not being as fully utilised as they might, given the nature of a particular airline's operating system.
5)Excess output. This is evident when more output is available than the demand coming forward to purchase it at a given price.
6) Spoilage.'Spoilage' occurs where seats fly empty
despite there being sufficient demand (at a given price) to have filled
them.
