Due to a miscommunication with Chase United, I was under the impression that to receive the yearly bonus of 10,000 miles I would have to spend $25k over the course of 1 year. Come to find out that year is a calendar year...

My current spending for the year is at $20.7k, is it possible to manufacture $4k over the next 2.5 weeks? If so could you please point me into the correct direction.
