No, but I'm planning a trip with parts in the sale period and parts outside.I didn't think the discount codes worked on sale/promo fares anyway?
So:
- Yes, it's my experience that entering the Travelbank number to search for Future Flight Credit fares, hides the Promo Code box.
- The promo codes don't work on the sale fares, but they work on some which are not much higher, and reduce the total below the sale fare by a few dollars.
- I have managed to buy the current sale fares, using FFC.
