OK, so you can buy the $600 ticket for 40K UR points each. The cheapest mileage seats I see are 35K Alaska miles roundtrip if you can find award seats.
Since you'll earn miles when you (1) buy the ticket and (2) fly the flights, you're earn more in miles than the 5K difference.
Just buy the tickets using UR on the dates you want and be done with it.
