I'm planning to go to Spain for half a year this March and stuck with booking flights.
I'd like to fly from Seoul to Seville and then returning flight from Frankfurt to Seoul and realized this is almost double the round-trip tickets which has exactly reverse leg on the way back e.g. ICN-SVQ-ICN.
I've already tried the "Open-jaw " and multi-city option but didn't make much difference.
Any idea? Please help!
Thank you in advance.
