and a perk w DL...........their miles do not expire............. unlike other airlines that have a 12 -month use it or lose it policy or others that require activity within 18-months, once you have DL SkyPesos in your acct they're there for life...........no activity required

But DL's redemption rates -- especially on ST partners -- are often much lower (e.g., DL award on SU to Geneva is 25k; SU charges 40k for it). And if you do make it to 50k MQMs, then your bonus is 100% and not 50% as on SU.
