According to a thread on a.net, NW moved in with Delta in Terminal C. Now that there is another gate available will Jetblue take A4? Will it remain unused (except for some overflow) due to the economy?
Update: It appears that the thread is wrong, NWA and SLCAirport.com show that all of NWs flights operated out of A4 today. But still it seems likely that this will happen, so when it does who will take it?
