Which airline dont charge baggage fees??? How do i find the best deal- do i go through airline or other? Looking for good roundtrip deal from Ontario ca or LAX to seattle for a family of 3 departure date June 11,12 or 13th returning on June 21 after 2pm Southwest doesnt charge bag fees but there are plane changes and we have a dd12 and dont want to deal with getting split up. American virgin and alaska had good deals but charge bag fees any advice ??
