I think you may have missed the previous posts on this: el cheapo's (or any fare) flown after March, booked through UA (016 stock) on partner carriers still will earn based on revenue, not distance flown (assuming they're eligible for mileage) when credited to MP. Even when earning based on distance, there are very few el cheapo's on partners, even booked through them, that give 100% anymore. But feel free to name some, if you can. AC, TK, LH, LX, LO, SA, SQ, TG, ET, etc. all have at least some, if not many, low fare classes that earn either 50% or zero mileage on el cheapo's to UA.
