This question already has an answer here:
Several months ago, I snagged a very cheap flight from London to Brittany (Quimper). I'm trying to persuade some friends to come out at the same time, but as it's much nearer the time, the flights are, well, not nearly so cheap today...
Thanks to our friends at LoCo2, I know how much it'd cost them to make the journey by train only. (The price comes out slightly more than my advanced flight price, but quite a bit slower). My supposition is that it might be cheaper + quicker if they flew to somewhere in France, then took the train the last bit. However, here's quite a lot of smaller airports that they might fly to, so a manual search isn't looking all that easy.
Are there any sites which allow you to search for a combined flight+train price, where you give a starting + ending city, and it finds connections?
(Basically, I'm after "HiCO2", something that'll give LoCo2 style train search results, but with one of the legs by plane)
