I personally am quite satisfied with redemption availability. In the last 12 months I have redeemed LHR-DEL-LHR once in F and once in J, DEL-HKG-DEL in J, BRU-YYZ-BRU in J. The dates have also been either exactly what I wanted or within +/-2 days.
Some here think 9W redemption rates are a tad high, but IMHO they are quite comparable to BAEC and LH M&M, my two other main programs. I also get a better F&J product on 9W for similar burn rates. Earn rates however are indeed somewhat lower on 9W (for eg. 225% for a Plat in 9W F, as opposed to 325% for a SEN in LH F or 250% for a BA Gold in BA F.)
