English Translation
Hong Kong International Airport is a busy airport.
This seems to have been added on tatoeba by a native speaker, but (1) it’s missing the accent on επίσημο, and (2) I can’t find any evidence on Glosbe or google that this is a common way to say ‘international’ airport. Επίσημο means something more like ‘official’, and the usual term for international airport is διεθνές αεροδρόμιο.
