I suspect OAK and RNO will make it back on the route map at some point.

OAK was good to get to Frisco in a pinch, especially when CO (briefly) had an EWR-OAK flight. Usually was cheaper than SFO and great u/g odds.

I loved Reno simply because it was so convenient to Squaw Valley, one of my favorite ski spots. Never flew into RNO for anything other than that so I suppose that may be one of the reasons it's going away. I believe NW canned their flight to RNO as well, so it looks like DL is the only SkyTeam game in town now. At least UA is in there for future ski getaways !
