Travel / Poland-Kaliningrad connection? [6]

I saw that there is no LOT connection between Pl-Kaliningrad, why? How people travel between these two places?
My question is not practical, rather theoretical, I'm interested about the background. How are the polticial-economical-tourist relations between them? I read some articles and I saw that they want to strengthen the ties, and make it easier to travel and such things, but how does it look in real life?

Language / Dzbanecznik as a synonym of alcohol? [10]

I need a Polish slang word for alcohol, in the meaning of a drink which relieves the troubles, makes you feel better, eases your pain or something like that. Or maybe it's not slang, it can be any synonym which is commonly used for alcoholic drinks. I only found this word, but as I saw it it seems it's not the best choice - i dont even know what it means actually :/

Thanks for any tips.

Hello!

I would like to ask about the usage of this phrase. Can we use it for human, or only for non living things? Can we use it with mieć, in a possessive context? For example:
