I need to fly from RDM to TUS Jan 25-28 on United Airlines for business. I'd like to make the most of my miles before Mar 1 and would like to put a mileage jog into the trip on Jan 25. The best I can figure is RDM-LAS-TUS-RDM. I am new to mileage runs and could use some advise.

I found this using the multi-destinations page on united.com. It includes a long layover in LAS which should be fine.

What if I am able to find another booking with multiple destinations and layovers and I don't make it to one destination before the next flight takes off due to a delay. Is there a way to put all legs on one itinerary?

Thanks,

Jonny
