Or you could book on US just like me and save some $$$.
I paid $344.40 all together for a flight this upcoming Oct 4. It involves a red-eye for the following routing: ELP-PHX-LAS-EWR with return as EWR-CLT-PHX-ELP.
I would love to take CO instead, but they don't have direct ELP-EWR flights as of now. And I am willing to pay $400+ R/T for such a ticket.
