In the last 18 months I have had three round trips and the daughter has had one on Southwest from Flint or Grand Rapids, and we have been very pleased with the cost/performance of Southwest Airlines.
And the worst advertising ever.
Fly to Florida for only $199 !!!1 *
* one way
Southwest has hardly ever been competitive in price even when I lived near Love Field.
I know some love them. But they’re gimmicky like every other airline.
