Several of the main flight search tools (Kayak, matrix.itasoftware.com) and the like either won't show or tell you they can't show flights to Cuba due to legal reasons and them being American websites.
Is there a search tool that will? I realise I could go to LAN or Copa or other airline's individual websites, but I'd rather there be an easier way to find flights from, say, DFW to HAV (yes I realise it'd most likely have to go through another country first).
