Thank you for the info.
Planning a 31-day business class award trip with my parents to NRT, HKG, Aust. & N.Z. Planning to ticket us seperately in case we have to take different routes to reach the stopover destinations at about the same time.
Does the re-ticketing each segment of the whole itinerary also kick in when trying to upgrade a cabin from the Economy I might go with to optimize the timing to business class that got more availability later?
Thanks again,
Steve
