This question already has an answer here:
In normal tickets, it would get all of your subsequent flights invalid once you miss a flight in the midst of the whole itinerary. How about the case on the RTW ticket?
Usually the RTW ticket doesn't allow you to change the route, but allows you to change the date of the flight. If you miss a flight, can you change the date of the (missed) flight after the departure date?
Or can I buy a separate ticket by myself to make up for the missed flight and resume the remaining part of the itinerary from the next city onward?
If the specific program is required, it is the Star Alliance award ticket redeemed on ANA mileage program. But I would like to get a generic answer, if possible.
