I'll be taking several long-haul flights over the next month. From previous experience I know I'll probably be getting a fair bit of single-use plastic. I am keen on minimising waste, particularly plastic. In my daily life I do this by avoiding anything wrapped in plastic - if it's absolutely unavoidable, I try to find a way to reuse it.
On a flight however, it seems like my options are very limited. I've thought about bringing my own cutlery, but I'm concerned the single-use cutlery provided will just get thrown out anyway. There's also the plastic coverings, which are probably recyclable, but I can't recall seeing them being separated from the general rubbish. There's probably things I haven't thought of as well.
What are some things I can do minimise the waste I am responsible for given that I'm on a flight? I also want to support organisations that are taking waste minimisation seriously. Are there airlines that are taking a pro-active approach to waste minimisation?
Edit: Thank you everyone for the answers. The general trend is order-of-magnitude arguments essentially saying if you take the flight, any other concern is insignificant. I want to make a few comments:
Firstly, no one has provided any data quantifying the environmental impact of 1kg CO2 emissions to (say) 1kg of single-use plastic that goes to landfill. Without this data then the arguments are heuristic at best (although I don't doubt which way the conclusion will fall).
Secondly, CO2 off sets are a thing, and if the companies providing them are to be believed, then your global warming contribution is negated. If that is the case, then the next thing to work on is the waste you generate.
