May 8, 2019 at 0:02 comment added JJJ @SpehroPefhany on regular airlines I think they would. Probably not if you ask for spirits or wine (do they still serve wine from glass bottles? Mostly been getting the small plastic single-use ones lately lol).
May 7, 2019 at 23:59 comment added Spehro 'speff' Pefhany I wonder if they'd fill my 20-oz travel mug with orange juice instead of those little one-gulp plastic cups..
May 7, 2019 at 21:22 comment added JJJ @Willeke nice, when using it for coffee you could use a thermos. ;)
May 7, 2019 at 21:16 comment added JJJ @Willeke that's an interesting one. How do you keep it clean? That was one of the caveats I thought of, especially on multi-day travels (e.g. multiple flights after each other). Do you carry a little soap dispenser or clean it in the toilets?
May 7, 2019 at 21:14 comment added Willeke I often need a mug while traveling, using it in the plane would not add to the weight I carry.
May 7, 2019 at 17:40 comment added JJJ @perennial_noob I'd say so. The argument by others is that the weight of the cup means more fuel is used which in turn offsets any environmental benefits from not throwing away the cup. Note that I (and I assume others here too) haven't done the math on this.
May 7, 2019 at 17:33 comment added perennial_noob That kind of reuse still means that you are contributing to less trashing, right? Even if the plastic stays on and is used by another passenger, it is better. Otherwise as a passenger I might as well use 3 cups of water for every one drink of water. The impact in the immediate short term being lower is a different argument but since when did it become cool to consume without scruples because it won't make a difference? In fact the other way, airlines may budget to carry multiple cups per passenger because of this trend of consumption.
May 7, 2019 at 17:08 comment added JJJ @HenningMakholm sure, but does it make one feel as good? The mug can be a conversation starter. Soon everyone will be flying with mugs. Airlines will feature their mugs (from the tax free catalogs) more prominently and in no-time everyone will be doing it. Mugolution! But yeah, in all seriousness, you're probably right.
May 7, 2019 at 17:00 comment added hmakholm left over Monica Based on numbers and arguments in the other answers, it looks like the extra fuel burn from flying with a mug can easily outweigh the environmental impact of producing and disposing of a plastic cup.
