That is in reference to moving the original booking date forward. Example... I am booked on JAL to depart on Dec. 12th. I want to take an earlier flight leaving on Dec 5th. JAL is booked. However, Malaysia has seats open that day. The question is can I switch to another OneWorld airline, like the Good Ole days?
