*airport

No; airport is American spelling. Aeroport is English (and a bit old fashioned, perhaps, but never mind). I had added both forms of sentence.

I'm usually a great fan of old-fashioned English, but this one was unfamiliar to me. Is it actually to be found in current dictionaries?

I searched through the Project Gutenberg collection of public domain books (a good source of old fashioned English) and did not find any uses of aeroport).

I think that it's only a French word. No references on dictionary.com.

Well, gosh. I very distinctly recall it having been "Christchurch Aeroport" when I was growing up, but now I can see little or no evidence for this usage, so I may just have to give up.

Next, someone will prove to me that "momentarily" always did mean "in a moment".

And a final check in the Oxford dictionary permanently spoils a childhood linguistic memory. Oh well. Perhaps they were trying to be cosmopolitan and French.

You can still go to Christchurch Aéroport, as long as you don't mind doing it in French. ;-)

If you can find a quote from an old book or magazine that would be great (I sneak back old English that way myself).

...or in Russian...

OK, it's aeroplane, and, if you're particularly atavistic, aerodrome (which I suspect is also in Slavic languages) for airport, but there really is no such thing as an aeroport in English. Alas.
