Engineering360: "Etihad flight goes single-use plastic free"

Well done to Etihad. Another step would be for all airline companies to leave the magazines (including the duty free ones) outside the planes, making it optional or digitized. This would save tonnes of unread paper flying around the skies (fuel and other savings would far offset the perfumes etc. sold)!

Also, customise the food/menu, thus avoiding tonnes of food being flown around thousand of kilometers before being discarded!
