WP:AIRPORTS is neither here nor there with this issue, so lets not flog that horse again! The relevant guidelines are WP:LEAD and Wikipedia:Naming conventions (use English)#Include alternatives. A useful quote from the former:
""If there is a significant number of alternative names or forms it may be helpful to keep only the most common two or three in the first paragraph and a list of them in a separate section or footnote to avoid cluttering the lead; see Freyr for an example of this.""
I do not think we should only have the alt names in the infobox. Thanks/ "
