That would be too good of a deal where one would only need to commit to a begining date, with free itinerary changes before the 1st segment is actually flown. Is this another benefit of buying a ticket in area 2 or 3 ?</font>
Yes. Also allowed to purchase tickets up to 1 hour before 1st flight (instead of 7 day advance) and no minimum number of days if I recall correctly. The point is that all of these rules vary by region and sometimes by country. Almost all of the rules outside of the US are more favourable, for some reason.
