BryanIAH, thank you for the suggestion.
I took a look at the fare rules and I'm not quite sure if I understand them correctly, if at all.
Information Taken from Korean Air website
Code:
Saver tickets:
Stopovers (*): Unlimited stopover permitted
Date Change: Outbound (**): Allowed. Charge 100 USD. If fare difference occur, charge fare diffrence +100 USD (certain flight restrictions apply)

Rerouting: Allowed. Charge fare difference +100 USD
(*) Please contact Korean Air customer service center for information on stopover service.(for qualified fares only)
(**) Outbound date change is subject to fare difference.
If I book a flight from LAX to ICN with a single 1hour 30min stop at NRT and I want to change my flight at NRT and board a flight from NRT to ICN a day later, would that qualify as a stopover or a date change?
Perhaps I shall call Korean Air customer service this afternoon.
