Berlin Brandenburg: The airport with half a million faults
If I may take an opinion on this having lived in Berlin for 2 years, perhaps the most frustrating aspect of this is that this new airport isn't just like a better, fancier one that'll replace an already adequate airport(s) - Berlin's existing airports (Tegel the 'main' one and Schonefeld the secondary) are, to put it mildly, an embarrassment for the captial city of Europe's biggest economy.They are quite simply awful, way over capacity, bad facilities, and also pretty inconvenient public transport links (Tegel especially). I honestly would rate both of them poorly if they were regional airports. Indeed, you'd be hard pressed to find a regional airport anywhere in Europe as bad as these.It makes flying in and (especially) out of Berlin pretty inconvenient, particularly internationally where you need to do a short hop to an actual  European international hub airport to even get a direct flight to most places (only direct long haul flight I ever got out of Tegel was to Abu Dhabi - to US, Latin America, etc, all needed connections first).To be fair Berlin has a unique culture as a capital and it's not your typical 'capital city' experience, but this is just basic infrastructure and really, really should be there. You pay a lot of tax, after all.
