is checked baggage free on delta
Regional service for the airline is served by Delta Connection. Delta typically charges a fee for all checked bags on domestic flights, with most international flights having an allowance of one or two free checked bags per passenger, depending on destination.
The Delta flight is cheaper. But check a bag at a cost of $25 for the first checked bag each way on Delta, and your total fare climbs to $256 -- more than the cost of the Southwest flight, which includes free first and second checked bags. Add a second checked bag for $35 each way on the Delta flight, and you'll pay a whopping $326.
