Talk:Metropolitan area airport codes

Necessary?
Is there a need for a list like this? It would seem best to put these in the articles in question. About the only reason I can think of to keep this is that these can sometimes come in handy for Round the world flights optimizing... (WT-en) Jpatokal 08:28, 27 February 2008 (EST)
 * If it didn't exist I doubt anyone would bother to write it. However, now it does exist and in a reasonably comprehensive form, I see no reason not to preserve and maintain it. Server space gets cheaper every year.
 * I can't see the utility in using multiple occurrences of the template, though and I will remove all but the first occurrence.  -- A l i c e ✉  08:16, 25 January 2013 (UTC)
