I just want to clarify something before I book. I want to book a particular route that doesn't have a ton of availability now early in my RTW and then I expect I'll push some of the later segments out because they're more than 365 days away from today, but not 365 days away from the first day of the ticket.
As an example, let's just say my route was JFK-LAX-MEL-SIN-LHR-JFK. If I changed the dates of the LHR-JFK flight before flying the JFK-LAX flight, would it prompt a reprice for the ticket fare? I believe from what I've read that if I wait until after I've flown JFK-LAX to rebook the date of LHR-JFK, it wouldn't prompt a reprice.
