What Is P4 Parking at Newark Airport and Where Is It Located?

P4 at Newark Airport is the official on-airport daily parking garage operated by the Port Authority of New York and New Jersey. It sits directly on airport property, making it one of the most convenient options for travelers who want to stay close to the terminals without dealing with off-site shuttles.

P4 is positioned closest to Terminal C, which is United Airlines' exclusive hub at EWR. The garage connects directly to the AirTrain Newark monorail system, which carries you to Terminal C in about 7 minutes, Terminal B in about 11 minutes, and Terminal A in roughly 20 minutes. You access P4 from the airport's internal road network — follow signs from the New Jersey Turnpike (I-95, Exit 14) or Interstate 78.

The garage is a multi-level structure with covered spaces, 24/7 access, and direct AirTrain platform access on-site. If you're flying United Airlines out of Terminal C, P4 is your most direct on-airport parking option. For Terminal A or B departures, P4 still works well — just budget a few extra minutes on the AirTrain.

How Much Does Newark Airport P4 Parking Cost?

P4 charges $4.25 per 30 minutes for the first three hours, then $8.50 per 30 minutes after that, capping at $60 per day for drive-up customers. Pre-booked reservations bring that daily cap down to approximately $38/day — a savings of about 36%.

Rates above are per Port Authority of New York and New Jersey published figures and verified lot data (verified April 2026). For a full breakdown of all official on-airport lot rates, see our guide to Newark New Jersey airport parking rates.

For trips longer than two or three days, the savings from pre-booking P4 add up fast. A five-day trip at the drive-up rate costs $300. Pre-book and you're looking at roughly $190 for the same stay — a difference of over $100.

How Do You Make a P4 Reservation at Newark Airport?

You can reserve P4 parking online through the Port Authority's official parking page at newarkairport.com. Here's how the process works step by step:

1. Go to the official EWR parking reservation page
2. Select your arrival date, departure date, and entry time
3. Choose P4 Daily Parking from the available lot options
4. Enter your vehicle details and payment information
5. Confirm your booking — you'll receive an email confirmation with a barcode or reservation number
6. On arrival, scan your confirmation at the P4 garage entry gate

Third-party platforms like those compared on Triply's EWR parking search may also list P4 availability alongside off-site alternatives. This lets you compare P4's pre-booked rate against off-site lots in one place before you commit. You can also check platforms like SpotHero or Way.com, but always confirm you're booking the correct lot and confirm the cancellation policy before paying.

Print your confirmation or save it to your phone. Most EWR parking gates accept mobile barcodes, but having a printed backup never hurts — especially for early morning departures when connectivity can be unreliable.

How Does the P4 Shuttle Service Work — and How Long Will It Take?

P4 does not use a shuttle bus. Instead, it connects directly to the AirTrain Newark monorail system, which runs on-airport between all terminals and the P4 garage. The AirTrain is free for travel between terminals and parking lots within the airport.

Here are the approximate AirTrain ride times from P4 (verified April 2026):

• Terminal C (United Airlines): ~7 minutes
• Terminal B (international carriers including Emirates, Lufthansa, British Airways, and others): ~11 minutes
• Terminal A (Air Canada, Alaska, American, Delta, JetBlue, United): ~20 minutes

Important 2026 construction note: The Port Authority broke ground in October 2025 on a $3.5 billion AirTrain replacement project. The new cable-driven system is scheduled to open in 2030. During construction, the AirTrain runs normal service on weekends and evenings. However, weekday suspensions from 5 AM to 3 PM are in effect throughout 2026. Free shuttle buses replace monorail service during those windows. Allow an extra 15–20 minutes if you're departing on a weekday morning. Check the Port Authority AirTrain project page for current service schedules.

How Does P4 Compare to Other EWR Parking Options?

P4 sits in the middle of the EWR parking spectrum — more affordable than the terminal garages P1, P2, and P3, but significantly more expensive than the on-airport P6 Economy Lot and most off-site lots.

P4 vs. Other On-Airport Lots

• P4 vs. P1/P2/P3: P4 is $10–$32/day cheaper at the daily maximum. Terminal garages are steps from their respective terminals but cost more. P4 requires the AirTrain, which adds time but saves money.
• P4 vs. P6 Economy Lot: P6 costs $21/day pre-booked versus ~$38/day for P4. P6 uses a dedicated shuttle (every 5–10 minutes). P4 uses the AirTrain. For budget-focused travelers, P6 wins on price. See our full Newark Airport P6 parking rates guide for a side-by-side breakdown.

P4 vs. Off-Site Parking

• Apex EWR Airport Parking: $8.95/day with valet and free 24/7 shuttle every 5–10 minutes — under one-quarter of P4's walk-up price
• The Parking Point (EWR): $9.95/day with real-time shuttle tracking via Silent Passenger system
• ABC Airport Parking (EWR): $12/day with free shuttle every 10 minutes to all terminals
• Newark Airport Long Term Parking (NALTP): $18/day, just 2–3 minutes from terminals with EV charging and a loyalty program

Off-site lots use their own shuttle buses, not the AirTrain. This means they bypass the $8.75/person AirTrain access fee charged to NJ Transit rail passengers — a real advantage for families or groups. For a complete comparison of off-site options, our guide to EWR long term parking options covers every major lot near the airport.

The main advantages P4 holds over off-site lots are covered parking, direct on-airport AirTrain access, and no reliance on a third-party shuttle operator. For travelers who value convenience and peace of mind over savings, P4 delivers.

Can You Cancel or Modify a Newark Airport P4 Reservation?

Yes — pre-booked P4 reservations can typically be cancelled or modified before your arrival date. The Port Authority's online booking system generally allows changes without a fee, as long as you make them in advance. Once you've entered the garage, the cancellation window closes.

Here's what to keep in mind:

• Cancel or modify at least 24 hours before your scheduled arrival to avoid any issues
• If your flight is delayed and you overstay your reserved period, you'll be charged at the standard hourly rate for any additional time
• The daily maximum of $60 still applies to overstay charges — you won't pay more than that per calendar day
• Keep your confirmation email; you may need the booking reference to modify or cancel online
• For third-party bookings, check that platform's individual cancellation policy — it may differ from the Port Authority's direct booking terms

Flight delays are common at Newark Liberty. If your inbound flight is late and your car sits an extra night in P4, the daily cap protects you from runaway charges. Budget accordingly for the extra day's rate when planning multi-night trips during busy travel periods.

What Are the Best Tips for Saving Money on P4 Parking at EWR?

Pre-booking is the single biggest lever for saving money at P4. Locking in your reservation online cuts the daily rate from $60 to approximately $38 — a saving of around $22 per day based on current Port Authority rates.

Here are more ways to reduce your P4 parking costs:

• Book early: Rates can increase as your travel date approaches and availability tightens, especially around holidays and summer peak season
• Compare P6 first: At $21/day pre-booked, P6 saves roughly $17/day more than P4. If you can handle a slightly longer shuttle ride, P6 is the smarter budget choice
• Consider off-site lots for multi-day trips: A 7-day trip at Apex EWR Airport Parking costs about $63 at their standard rate. The same trip at pre-booked P4 costs around $266. The difference is over $200
• Use Triply's EWR parking search to compare P4 against off-site lots before you book — you may find a better match for your trip
• Enroll in TSA PreCheck: Faster security means you don't need to arrive as early, reducing the chance of needing short-term overflow parking. TSA PreCheck enrollment takes about 10 minutes and the benefit pays off on every trip
• Avoid peak pricing windows: Thanksgiving, Christmas, and Memorial Day weekend tend to see higher demand. Book at least two weeks out for those periods

Is P4 Parking at Newark Airport Safe for Overnight Stays?

P4 is a Port Authority–operated garage with 24/7 staffing, security cameras, and controlled access — making it one of the safest overnight parking options at EWR. The structure itself is covered, protecting your vehicle from weather as well as visibility concerns.

Key security features at P4 include:

• 24/7 on-site Port Authority security presence
• Video surveillance throughout the garage
• Controlled gate entry and exit with ticket or reservation scan
• Well-lit interior on all levels
• Direct AirTrain access eliminates the need to walk through unlit surface areas at night

EV drivers will also be glad to know that P4 has electric vehicle charging stations on-site. You can verify station availability and compatibility using ChargeHub's P4 station listing before your trip. This makes P4 one of the few on-airport options where EV owners can charge while they travel.

For travelers with mobility needs, P4 includes ADA-accessible parking spaces on designated levels with direct access to the AirTrain platform. If you need a specific accessible space, arrive early — these fill quickly on busy travel days. The Port Authority's parking customer service line can confirm current accessibility arrangements before you book.

2026 Construction Update: What P4 Parkers Need to Know

Newark Liberty is in the middle of a multi-billion-dollar redevelopment that affects how you get from P4 to your terminal in 2026. The biggest impact is the AirTrain suspension schedule.

The $3.5 billion AirTrain Newark replacement project — which broke ground in October 2025 — suspends weekday service between 5 AM and 3 PM throughout 2026. Free shuttle buses cover the gap. If you're departing on a weekday morning, build in an extra 15–20 minutes compared to normal AirTrain travel times.

Other active projects that may affect P4 parkers:

• Terminal A is now fully open — the $2.7B rebuild completed in 2023 with 33 gates. If you're parking at P4 for a Terminal A flight, budget for the ~20-minute AirTrain ride (or longer during weekday construction windows)
• Terminal B is slated for full demolition and rebuild under the Port Authority's 2026–2035 capital plan. No construction start date has been set yet, but procurement is expected to begin in 2026–2027. Monitor the EWR construction advisory page for updates
• Road network changes are proposed as part of the capital plan — check real-time conditions before driving in

Despite construction activity, P4 itself remains fully operational. The garage access points and AirTrain connection are not directly affected by the current phase of work.
