Confirmed for less gives you Sky Miles and indeed is therotically refundable. But just like a normal Delta passenger "fare rules may vary." In my experience it's not worth the miles. On one occasion I had to change the outbound when my kid got selected for a once in a lifetime nationally televised music performance. The change fees exceeded 50% of that particular leg, but here's the really bogus aspect: the change prompted reissue if the entire round trip, and the good deal fare the pricing had been based on was no longer available. Approximately $280 RT turned into $850. So I decided to tell them to pound sound ( in the words an employee can get away with) and decided to standby outbound and use the return Fly Confirmed For Less as originally issued. Turns out that's not allowed! Turns out, if you don't board the first ticketed flight, the balance is invalid. Imagine trying to get out of Florida during spring break after having your positive seat jerked! It was a nightmare! Not to mention money down the drain. I think I got a $120 refund. And an additional $300 penalty in the form of unanticipated hotels. Spousal wrath and impact of kid missing school: priceless! So the additional 5% savings between the Fly Confirmed categories is good money in your pocket vs. too much risk in case of change and the points are an easy bypass, since the program is much less generous than it used to be and the points expire. Fly Confirmed for Even Less is your friend, always resulting in a slam dunk best price in the market, no matter how hard you shop rival carriers on Expedia or whatever. There's nothing like knowing you're going to get there, especially when there's money at stake ( cruise, condo, hotels, etc.) or simply precious family experiences that can be recalled in a fond way .... or not. I highly recommend FCFEL!
