ITA is showing some horrible routings on AF, like going from CDG to BCN and then to SVQ often with an overnight layover.

Or you fly into CDG and then go ORY-SVQ in under 2.5 hours.

If I go from SFO to BCN or MAD via CDG, it's under 15 hours each way. But try to go to SVQ and the return is 25 sometimes 31 hours because of the routing and overnight layovers!

Probably make more sense just to fly in and out of MAD or BCN and take the train to SVQ?
