Ridiculous subjective list. Much as I detest Schönefeld I could not objectively rate it as worse than Lagos, for example. But if you're booking on eDreams, you are (as EI-A330-300 suggests) likely to be European-based, and I'd add you are probably travelling for leisure, and you are potentially not the most savvy traveller (I certainly don't think of eDreams as the best or most effective OTA...)
