Unless ANA is doing things very differently than other major airlines, the office it has in Washington DC is primarily a ticketing office.  United, American, Aeroflot, Air France, Japan Airlines to name just a few all have similar facilities within a block or two of the ANA office.  It doesn't make sense within the context of that article - to me anyhow - to highlight just one of several airlines with offices here; or, for that matter, to single out "airlines" given the number of other major entities (trade associations especially) with a presence in DC.  Is there something about the ANA office that sets it apart from other airlines or other entities that have established a presence in Washington?
