Hi,
Not to mention that the thing's lighter, requires one less donk and one less full-time crew member (which makes it more economical to run)
In my opinion it is the heart of the problem
A plane (was) should be a means of transport which allows to go quickly from one point to another and is relatively expensive for passengers and must be of an acceptable return for its owners (airlines)
A plane must now be a means of transport which allows to go from one point to another (but now the emphasis is no more on speed ! ) and to be inexpensive for passengers and who must have a return to report the maximum possible for its owners (now mainly banks and shareholders)
This is also the other side of progress
Progress is being made in terms of economy and efficiency ..
