Kansas City has been a very popular fare war market recently and there are some pretty nice mileage run fares out there today from SFO & SEA on American, Delta and United from either $89 or $99 one-way base roundtrip.
The routing rules are again generous on United (and even Delta from Seattle allows SEA-ATL-MCI!), so there are some opportunities out there for sub-4.0cpm mileage runs.
Here’s an example (below) on United from San Francisco. Be sure to check out your options on American and Delta, too. I’m on the road today, so can’t commit the time to check further.
