One of the benefits of a FLEX ticket is (IMHO) the ability to do a same day change to an earlier and maybe even later flight without having to pay a change fee and the fare delta. This is especially valuable on the return portion of a ticket and/or if you are flying on a busy route with many daily flights. I did use FLEX tickets if I wanted to secure a modest fare far out, expecting a rather high probability that I need to rebook once or twice before actually using the ticket. Paying multiple change fees or fare deltas did offset the additional cost of the FLEX fare for me. Just my $.02
