I've found some interesting flights using Matrix Airfare Search that involve Turkish Airlines. The problem is that these flights are like this:
Go: MAD - DEL
Return: BOM - MAD
Matrix Airfare Search cannot book flights and send me to the Turkish website, but I cannot find any way to book return tickets that have a different return city (and if I book two only one way flights the sum of prices do not match the Matrix result). How can I book this?
EDIT: Using the multi-leg searcher, the prices don't match the prices offered by Matrix. It matches the sum of prices of the individual legs.
