Why has cargo planning become a lot easier?

Typically Cargo is an afterthought in most passenger airlines in terms of schedules, equipment, and profitability. Finding the value of cargo given a passenger schedule is a very cumbersome and laborious exercise for the cargo revenue management and network planning teams. In most airlines, the process kicks off with the passenger network team that passes out a medium-term schedule (2 – 3 years) and short-term schedule (up to 1 year) based on passenger demand on an origin-destination basis.
