You seem to state that once a ticket is issued and once the 1st flight is flown, no changes to the base price. I did fly on a AONEx ticket in the previous decade where my ticket was issued just before any price increase. My concern is that some airlines have changed the price, while others have not updated their fares. The airline that issues the ticket was using the wrong price to begin with.
