Greetings from Poland. I’m here with work and yesterday I did my first flight whilst being plastic free. I travelled to the airport early so I could have a meal before my flight (instead of grabbing a sandwich for the plane as usual). I took my own water bottle also, although I bought a tea on the flight and they insisted I have the plastic lid.
However I managed to stay pretty much plastic free once here as, just by luck, next to our Airbnb place is a wonderful market selling fresh fruit and veg. not only plastic free, but super tasty as all locally grown and freshly picked! Yummy!!
