Fly Confirmed for Less is pretty much useless for mileage upgrades. INT'L requires an underlying Y,B or M Fare and Domestic required a K or higher. Since you can't specify fare class when purchasing FCFL, you'd have to spend time finding flight(s) where that's the lowest fare class being sold. Then there's the issue of upgrade inventory, If that's not available at purchase, it probably won't happen and you've way overspent for a regular main cabin ticket, not even C+. If you have Medallion Status you are eligible for Medalllion UG's.

I've never done it with a FCFL ticket but you can call and get a quote in $ and miles to upgrade to the appropriate fare class. Most of the time, the change fee will be waived. It won't be cheap though.

I do have another question. Tickets purchased in the US are subject to the "24 Hour" rule. You can cancel the ticket for a full refund within that time frame (Delta even extends it to midnight of the next day). Does that also apply to FCFL and/or FCFEl tickets? I'll probably ask our son to contact the pass bureau about that.

Every time I ask him to list us or buy FCFL, I come up with more questions.

mrs767er, I agree 1000%, the AMEX Card(s) can be great if you use the benefits.
