Disclosure: ParkingAccess cannot book parking at Ontario International Airport. This page lists the airport's own parking and is for information only. ParkingAccess sells parking reservations at other airports, including LAX and Burbank, and earns a commission plus a $9.95 service fee on those bookings.
Ontario International Airport's own lots charge a daily maximum of $20 to $35 for self-parking and $40 for valet, and pre-booking takes 10% off self-parking in Lots 2 General, 3, 4 General, 5 and 6. Lots 5 and 6 are cheapest at $20 a day ($18.00 pre-booked), with a shuttle and a short walk to Terminal 4. Lot 3 is $25, Lot 2 General and Lot 4 General are $30, and Lot 2 Premium and Lot 4 Premium are $35. Lot 1, for international arrival travelers only, has a $20 daily maximum. A week in Lot 5 costs $140 at the posted rate, the same as at LAX Budget Parking.
What each ONT lot costs
All ONT lots are on airport grounds and all are cashless. The daily maximum covers each 24 hours in the lot. Lots 3, 5 and 6 and valet charge only a day rate, so even a short stay costs a full day.

|---|---|---|---|---|
| Lot 1, International Arrivals Terminal | $6 | $10 | $20 | Not available |

Pre-booked prices apply the airport's flat 10% self-park discount, and the airport's pre-book site shows the exact price for your dates. Valet can be reserved on the airport's valet site, with no published discount.
For bookings made through November 1, 2026, the promo code DECADE takes another 10% off pre-booked Lots 3, 5 and 6, for travel by December 31, 2026. Book at least seven days ahead. It does not cover Lots 2 or 4.
The rate list shows no tax note and no effective date. The fee estimator says fees include the City of Ontario parking tax, and the pre-book terms say booking prices include all applicable taxes. The tax rate is not published. A lost ticket pays the maximum. No maximum stay is published.

Shuttles run every 5 to 20 minutes, less often between 12:30 and 3 a.m., and stop on the terminal islands between the lots and the buildings, per the airport's shuttle page.
What 3 and 7 nights cost in each lot
A week in Lot 5 or Lot 6 costs $140 drive-up or $126.00 pre-booked. A week in Lot 2 General or Lot 4 General costs $210, or $189.00 pre-booked.
| Lot | 3 nights, drive-up | 3 nights, pre-booked | 7 nights, drive-up | 7 nights, pre-booked |
|---|---|---|---|---|
| Lot 5 or Lot 6 | 3 × $20 = $60 | 3 × $18.00 = $54.00 | 7 × $20 = $140 | 7 × $18.00 = $126.00 |
| Lot 3 | 3 × $25 = $75 | 3 × $22.50 = $67.50 | 7 × $25 = $175 | 7 × $22.50 = $157.50 |
| Lot 1 | 3 × $20 = $60 | Not available | 7 × $20 = $140 | Not available |
| Lot 2 or Lot 4 General | 3 × $30 = $90 | 3 × $27.00 = $81.00 | 7 × $30 = $210 | 7 × $27.00 = $189.00 |
| Lot 2 or Lot 4 Premium | 3 × $35 = $105 | Not available | 7 × $35 = $245 | Not available |
| Valet | 3 × $40 = $120 | No discount published | 7 × $40 = $280 | No discount published |
Each night counts as one 24-hour day, covering stays of up to 72 or 168 hours. How a partial extra day is priced in the self-park lots is not published; at valet it counts as another day. Pre-booking saves $14.00 on a week in Lot 5 or 6.
With DECADE, a pre-booked week in Lot 5 or 6 costs $112.00 or $113.40, which is $16.00 or $16.20 a day. The airport does not say whether the extra 10% comes off the full rate or the discounted one.
How pre-booking works
- Book on booking.flyontario.com up to 2 hours before you arrive. Pay online by PayPal, Visa, Mastercard or American Express.
- Scan your confirmation's QR code at a pre-book gate of the lot you booked. It covers one entry and one exit.
- Change or cancel at least 6 hours before arrival; cancelling costs $7.50. The $1.00 cancellation protection waives that fee and lets you cancel up to your entry time.
- A 6-hour grace period applies on arrival and exit. After that, extra days are charged at the lot's posted rate.
ONT or LAX: the parking bill for a 7-night trip
Drive-up, a week in ONT's Lot 5 costs $140, the same as LAX Budget Parking and $105 less than LAX Economy Parking. LAX's pre-book prices start lower than ONT's pre-booked rate, but they are starting prices that vary by date. ONT's terminal-front lots cost half the LAX Central Terminal Area rate.
| 7 nights | Drive-up | Pre-booked | To the terminal |
|---|---|---|---|
| ONT Lot 5 or Lot 6 | 7 × $20 = $140 | 7 × $18.00 = $126.00 | Shuttle, or walk to Terminal 4 |

| LAX Budget Parking | 7 × $20 = $140 | From 7 × $13 = $91 | Free shuttle every 20 to 25 minutes |
| LAX Economy Parking | 7 × $35 = $245 | From 7 × $15 = $105 | Free 24-hour shuttle |
| LAX Central Terminal Area, P1 to P7 | 7 × $60 = $420 | From 7 × $48 = $336 | Structures in the terminal area |
LAX figures are Los Angeles World Airports' posted daily maximums and "Pre-book from" prices from its parking rates page on flylax.com and pre-book site, parking.flylax.com, read September 17, 2026. LAX includes the 10% Los Angeles City Parking Occupancy Tax in its drive-up rates, and ONT says its fees include the City of Ontario parking tax.
The table leaves out the drive, fuel and flight choice. ONT says it has up to 90 nonstop flights to nearly 30 destinations. LAX may impound cars parked more than 30 days; ONT publishes no limit.
If LAX suits your trip better, our LAX parking guide lists the off-airport lots ParkingAccess sells there. You can also compare parking at Hollywood Burbank Airport, where ParkingAccess also sells parking.
