I have a FRA-QKL-FRA trip coming up on a D fare, due to change in meetings schedule I might need to skip FRA and fly to CGN direct. Due to cancellation penalties and higher one way fare, it is cheaper to skip the FRA-QKL segment and use the return portion only rather than cancel the ticket altogether and book a new QKL-FRA one way.
I assume from the above posts that if I OLCI the FRA-QKL segment and don't turn up, I should be able to use the return portion QKL-FRA as originally booked.
TIA.
