Judging from the comments on the OP, people are having trouble picking two airports that work - bit of a shame, to get lifehacker exposure and then having people shrug and go away. The problem is that I suspect adioso uses cookies and/or browsing history to figure out an itinerary to suggest (I received a default search suggestion that was so wacky for anybody except me, who had indeed done such a search elsewhere), but that suggested itinerary is practically guaranteed to fail given the small coverage at this point. It really would be better in this case if there was a bit less cleverness and the suggested search was one that the engine can actually fulfill. Anyway, LGW to ATH will work for those who want to try it.
