When you buy a ticket you have, as the name implies, a 24h period for FREE changes in routes, times, name... anything. You can even do a RT from a different airport, if you ask (something you can't do when booking), i.e. BCN - BRU, CRL - GRO. You can only touch two countries, though.
Wow - I never knew about the grace period ... let alone being able to change the routing. Can you do the routing change online yourself ?
Although, I find it's sometimes cheaper to book to singles separately anyway.
