On the topic of conservation, I hope all airlines would go the southwest (and some international airlines route) and dispense the popular drinks from large packages. For example, the cola - so many people consume it and a 2L bottle will get used up in a flight. It is better than carrying so many cans - both environmentally and financially.

Pinch pennies smartly.
