Changing Multi-City Business Ticket after first flight
I have a multi-city itinerary booked departing tomorrow and spans 2.5 weeks, all flights are booked in "J" fare class. I know I will have to change the last leg of my flight but won't know until after I depart on the first leg tomorrow. Any thoughts on if this will be really expensive if change after departure vs. before departure?
I'm thinking I could change it now and take a guess that's potentially safe.
The last leg of my flight is NRT-SIN-SYD with just a layover, and I need to split it to do NRT-SIN (stop over for a few days) then continue on SIN-SYD.
No routing/cities/destinations would change, just splitting the last leg and including a stopover in Singapore.
