Usually, we can see many cargo flights operating between 2 foreign countries (and even as domestic flights within a foreign country in some cases). There are passenger flights that operate in the same way, but they are much fewer in number.
For example, this is an image of Fedex planes flying over Asia, and none of them originate/terminate at US:
But if you take any passenger airline, then it is very unlikely that they will have so many 5th and 8th freedom flights. Why do more cargo flights than passenger flights enjoy these freedoms?
So, what's happening here? Are cargo airlines awarded 5th and 8th freedom rights more easily, or do passenger carriers simply don't apply for them, frequently, or something else?
