I was granted a 1P Challenge on August 19th (email arrived at 5:22 CST). It said I have 90 days to fly 15k miles. Which, based on my math means I have to do it by the 17th of November. I am flying CLT-ORD on the 16th of November. Will United still grant me 1P (will be 120 miles short before the 16th) even if the miles don't post until the 18th?

Talk about cutting it close.

Thanks
