Apart from the fact that certain destinations are only available for online award redemption on one or the other, in the past month or so at least, have they not been returning the same results? I noticed results got a lot spottier on nwa.com recently and figured the nwa.com search engine had been switched over to Delta's. Unless the award redemption system is improved on delta.com, I will probably be leaving once I use all my miles. I really hate having to call to do anything, much much rather do everything online. Given how many partners Delta has and the fact that only like what, 5?, are available for redemption online, I refuse, once I go down to Silver next year, to pay to redeem miles over the phone for the partners that require calling.
