Southwest airlines flights — Philadelphia, PA

Last updated: September 24, 2026

What affects the price

Flight pricing shifts constantly based on a few key factors. When you book your seat matters most, as last-minute tickets often come at a premium compared to planning ahead. The day of the week you choose and the specific time of your departure can also swing the total, as weekend flights are generally pricier than those mid-week. Demand during peak travel periods inevitably pushes costs higher, while flexible itineraries often reveal better deals. Get exact pricing confirmed free on the call.
