Guess these IATA airport codes for the representative world cities that actually start with the first three letters of their names in English. (eg. if Barcelona was BAR and not... BCN).
Some work if abbreviated, or if using the Anglicized spelling (eg. Ü as UE)
I agree with the other comments. Nuremberg doesn't comply with your instructions. Your main instruction say "..with the first three letters of their names in English". This conflicts with your supplementary note. I'm not sure what the proportion of Jetpunk users who know how to transliterate the Ü to UE
I would suggest you remove Nuremberg and replace it with another (LUX is a good suggestion) or update your instructions.
