Nowadays tickets are very expensive. I don't think that
entertainment or meals during a flight is good
idea. By banning this you can save many money
and make your flight more comfortable and cheaper.


First of all, meals on an airplane should be banned because
this can cause the airplane dirty. Passengers should wear
their zones and not eating during the flight. Furthermore
passengers can take with them something like chips,
a small sandwich or even a snack.


On the other hand, if meals and entertainments banned
during a flight, passengers may get bored and don't
want to fly again.


To sum up I think that this shouldn't happen because
flight would be rapid declined.
