Do people think as long as you travel in June but say after 5/25 you make a same day flight change or alternatively a date change, will the 3x points still post?

I vaguely think for same day changes it may still work, but I'm not 100%? I know they do reissue and exchange your ticket for a same day change, it generates a new ticket# although you do typically still automatically receive the online booking bonus even though the exchange transaction for the same day change was done by phone.
