Dude chill out and stick to what you know. As many people have stated over your several strange posts - there are professionals well versed in the industry that are able to run it fine. Yes there are several points that could be improved in my humble opinion but you look at them all seperately rather than together. Airlines have limited resources ie. income from pax/cargo, and assign this to what they believe is the most cost effective way. But you only seem to continually criticise the airlines. Individual security checks at each gate? Recalculate fuel costs etc on a daily basis? What if u purchase a ticket some time in advance and the cost of fuel goes up hugely? You then have to pay more before being allowed on? You would be well advised it is a business and creating computer programmes to do this, adding extra dutys to cabin crew to swipe your card either at the start or during an already busy service really is lunacy. And carrying several different meals for variety just shows a lack of appreciation of the logistics involved. Weight is at a premium as indeed are space and time. Drinks on flights are not free as you say, they have already been paid for when paying your ticket. Paying for these will not stop drinking excessively, but lead to accusations that crew are taking advantage of drunk passengers who keep paying for drinks on the longer routes. People dont want one-class aircraft, they want choice - like when the drinks trolley comes round! Major airlines make huge amounts primarily from first and business - especially on the north atlantic routes. Videos on demand and at a set time, having discussed it with the cabin staff during the flight is hugely unrealistic. It would require some sort of system operator to input it all thus adding a member of crew on every flight that will need to be paid for by you. May I take this time to remind you the crew are there for your safety primarily.
I could go on but have lost interest, suffice to say your several rants, make sense when looked at independently perhaps, but the reality of the industry, logistics and stated desire to keep things competitive contradict everything you say.
