I was reading the rules from this sticky. Just wanted to be absolutely clear - I was reading that the first international segment is not changeable, does anyone know how strict this is being enforced e.g. will they let changing flight time (but still same day) go? Reason I ask is, I am planning a RTW ex-NRT but I prefer not to stay overnight in Tokyo .... but I am concerned if my flight into NRT is delayed/cancelled and missed the first international segment (e.g. from NRT to ICN). Thanks.
