Just a note, I have been several airports in the top 50 and I certainly do not agree with the rank. I don't know how they measured it, but I don't understand how Singapore can rank that high, I found it close to terrible while visiting. Furthermore, I would rank Copenhagen much higher than e.g. Zürich. I don't use lounges, perhaps they represent a major part of the rank.
