Looking for flights to San Francisco from Indiana in September?
Southwest has round trip tickets IND–>SFO–>IND for $166 each way right now for a per person round trip of $332 plus taxes & fees.
Leaving IND Wed 9/17 and flying back the following Wednesday 9/20
Their flights include free bags and less than $250 round trip is a pretty good price in my observation.
They are also running a promotion for other cities right now as well.
Detroit flights are a bit more expensive on Southwest at $190 each way for the same days, so a per person round trip of $380 plus taxes & fees.
