Oh MANNN, yes, that would be awesome indeed @coruscate! Your search for cheaper flights is more serious than mine, I'm in Europe already so it's no comparison. I think you can search for the cheapest flight anywhere in Europe and see if you can take a Flixbus to Krakow - might save you a few dollars.
DM me on Discord if you have any questions about travel in Europe. We'll meet in november!
I've heard about Flixbus! Definitely going to look into that as an option. Thanks for offering to give me advice on traveling in Europe too. I will definitely be taking you up on that as I start planning things. :)
