Trying to hit gold on my US trial and am going to need 4057 miles before April 1. I'm based in Boston and am available on the following dates:

3/3-3/5
3/9-3/11
3/23-3/25

I've been searching PHX, LAS, LAX, SNA, DEN (via CLT) and can't find anything under $360. I'm not opposed to doing same day turns/red eyes, etc. Any help from the pros out there? Keep in mind that because it's on my trial preferred status it needs to be booked through US and on US metal only. Many thanks.
