Making air flights healthier

On a recent international flight, I counted sixteen alcoholic drinks on offer, along with "an international selection of beers". Not to mention coffee (three varieties?) and something like a dozen varieties of tea.

However, everyone knows that it is NOT good for your health, on long flights, to consume tea, coffee or alcohol!

So what was the choice if one wanted to do what IS good for health? There was sparkling/ aerated water (not as good for health), normal/non-aerated water, tomato juice or two kinds of fruit juice!

The fact of the matter is that there are at least as many kinds of fruit juice as there are of alcohol, but you would never guess that given the choice available in most public places.

Moreover, any form of alcohol is more EXPENSIVE for airlines to serve! Quite apart from the problems it creates with some passengers who over-indulge!

So why do airlines encourage passengers to indulge in more costly and unhealthy drinks, rather than less costly and more healthy drinks?

It will decrease stress on all airline staff, reduce costs, and make everyone healthier if all alcoholic drinks are banned from flights lasting more than say two hours.
