Complete Southwest PHL Terminal Guide [2026]

Last Updated on August 26, 2026 by Daniel Globe

If you’re flying Southwest Airlines from Philadelphia International Airport (PHL), head for Terminal E. Southwest’s ticketing, gates, and baggage claim are located there. The details that matter after you arrive have changed, though: Southwest now uses assigned seats and a new boarding system, and checked bags are no longer automatically free on most fares. Here’s what to know before you go.

Terminal E: Southwest Airlines’ Home at PHL

Philadelphia International Airport lists Southwest Airlines’ baggage claim, gates, and ticketing in Terminal E. You can confirm the airline’s current terminal information in PHL’s official airline directory.

Southwest operates Boeing 737 aircraft, but individual destinations, schedules, and gate assignments can change. Instead of relying on an old route list, check your Southwest reservation or PHL’s live flight information shortly before leaving for the airport.

How to Check In and Clear Security at PHL

Southwest gives you several ways to check in. Online check-in opens 24 hours before the flight’s original scheduled departure time. You can check in through Southwest.com or the Southwest app, or use an airport kiosk or staffed ticket counter when available.

If you already have your boarding pass and are traveling only with carry-on luggage, you can normally proceed toward security. If you need to check a bag, print a boarding pass, or get help with your reservation, use the Southwest facilities in Terminal E first.

Southwest passengers near Terminal E normally use the shared Terminal D/E TSA checkpoint. Philadelphia International Airport currently lists both standard screening and TSA PreCheck at D/E, with PreCheck available during designated hours. Because checkpoint hours and wait times can change, check PHL’s current security checkpoint information before traveling.

In a standard TSA screening lane, travelers should be prepared to remove shoes and larger electronics such as laptops when instructed. Eligible TSA PreCheck passengers generally receive expedited screening and can keep shoes on and qualifying electronics inside their bags.

PHL generally recommends arriving well ahead of your flight, especially during holidays and other busy periods. A practical baseline is at least two hours before a domestic flight and about three hours before an international departure, with additional time if you need parking, bag drop, accessibility assistance, or document checks.

Southwest Assigned Seating and Boarding at PHL

Southwest’s boarding system changed significantly in 2026. The airline transitioned from open seating to assigned seating on January 27, 2026. You no longer board and choose any empty seat simply because you checked in early.

Your seat options depend on your fare, Rapid Rewards status, and eligible credit-card benefits. Current fare rules generally work like this:

• Basic: a Standard seat is normally assigned at check-in unless you qualify for another seating benefit or purchase an available seat.
• Choice: includes selection of an available Standard seat at booking.
• Choice Preferred: includes an available Preferred or Standard seat.
• Choice Extra: includes an available Extra Legroom, Preferred, or Standard seat.

Southwest also replaced its old A/B/C boarding positions with boarding Groups 1 through 8. Boarding priority can depend on your fare, seat type and location, Rapid Rewards tier status, and qualifying credit-card benefits.

Southwest Baggage Rules at Philadelphia Airport

Southwest’s former blanket “two bags fly free” policy is no longer the standard rule. For U.S. mainland travel booked, ticketed, or changed on or after April 9, 2026, Southwest’s current optional-travel-charge table lists the following standard checked-bag prices:

• Basic: $45 first checked bag; $55 second checked bag.
• Choice: $45 first checked bag; $55 second checked bag.
• Choice Preferred: $45 first checked bag; $55 second checked bag.
• Choice Extra: first two checked bags included.

Exceptions apply. For example, qualifying A-List or A-List Preferred members, Rapid Rewards primary credit cardmembers, active-duty military travelers, and some other eligible customers can receive one or more free checked bags. Because benefits and itinerary-specific charges vary, verify your reservation before paying.

A standard Southwest checked bag can weigh up to 50 pounds and measure up to 62 linear inches when length, width, and height are added together. Oversize, overweight, and additional-bag charges can apply.

Southwest still includes a standard carry-on bag plus one personal item at no additional charge under its current mainland fare table.

What Amenities Does Terminal E Offer?

Terminal E provides food, drinks, grab-and-go choices, retail shops, seating, restrooms, and other standard airport services. Because concession locations and opening hours can change, use PHL’s current airport directory or map rather than relying on an old restaurant list.

Free Wi-Fi is available throughout PHL’s terminals. The airport also provides charging stations throughout the secure area, including multiple Terminal E locations. Southwest and other operators also provide power near selected gate areas.

If you’re traveling with a service animal or pet, PHL also has an indoor animal-relief area in Terminal E near Gate E-1, plus outdoor relief locations elsewhere around the airport.

Getting To and From Terminal E

Philadelphia International Airport is directly connected with Center City by SEPTA’s Airport Line. For Southwest passengers, the relevant rail stop is Airport Terminals E & F.

SEPTA currently operates Airport Line trains about every 30 minutes, and the trip between the airport and Center City takes roughly 25 minutes depending on the station and train. Check the PHL public transportation page or current SEPTA schedule before travel, especially late at night or during service changes.

Rideshare and Taxis

After collecting your luggage, follow the airport’s Ground Transportation signs. App-based rides such as Uber and Lyft use Ride App/Zone 7 on South Commercial Road outside the baggage-claim areas. Taxis use Zone 5.

Only accept a rideshare or taxi from the designated pickup area or an authorized driver. PHL specifically advises passengers not to accept unsolicited rides from drivers approaching them inside or outside the terminal.

Driving and Parking

If someone is dropping you off, follow airport signs for Terminal E and Departures. Drivers collecting an arriving passenger can use the designated arrivals area or PHL’s free Cell Phone Waiting Lot until the passenger is ready.

PHL offers terminal garages, short-term parking, and an Economy Lot with shuttle service. Availability, closures, and rates can change, so check PHL’s current parking status before driving to the airport rather than assuming a particular garage will be available.

Connecting Between PHL Terminals

Once you have passed through security, PHL’s terminals are connected on the secure side. That means passengers can generally walk from one terminal to another without leaving the secure area and going through TSA again.

PHL also operates an airside shuttle serving Terminal F and selected stops near Terminals A/B and C/D. It should not be treated as a general shuttle circulating through every terminal. For a connection involving Terminal E, walking through the connected concourses is often the straightforward option.

If both flights are Southwest-operated at PHL, Southwest’s current airport listing places its gates in Terminal E. If your itinerary includes another airline, check the operating carrier and departure gate rather than assuming the connection will remain in Terminal E.

Tips for a Smoother Trip Through Terminal E

Review PHL’s official airport map before arriving if you are unfamiliar with Terminal E. Knowing the relationship between Southwest ticketing, the D/E security checkpoint, baggage claim, and the Terminal E/F rail station can save time.

Keep the Southwest app or mobile website available for your boarding pass, assigned seat, boarding group, and flight-status updates. PHL’s flight displays and website are also useful for checking gate changes and airport conditions.

If you’re checking bags, confirm whether your fare or Rapid Rewards benefits include them before arriving. The difference between a fare with bag benefits and one without them can materially change the cost of your trip.
