Green Lot

100 feet from the terminal, but priced like remote parking

The Green Lot at Portland International Jetport sits about 100 feet from the Main Terminal, so it feels more like an economy garage than a true remote lot. It’s marked as long-stay parking and runs at $15 per day, which undercuts most on-airport garages in this region by a few dollars. If you’re leaving the car for more than two days, the daily rate usually beats app-based off-airport options once you add rideshare or shuttle tips.

Green Lot is set up for long stay use, so think trips of three days up to a couple of weeks. You park, walk the roughly 100-foot path toward the Main Terminal, and go straight into check-in on the departures level. No shuttle time, no guessing when a van shows up. For early flights out of PWM, that short walk can easily save 10–15 minutes over off-airport parking plus a van ride.

At $15/day, a 5-day work trip runs about $75, and a 10-day vacation hits around $150 before taxes or fees. That’s usually cheaper than leaving your car in the closer short-term options, which are priced for drop-offs of a few hours up to a single overnight. If you’re comparing off-airport coupons, factor in two rideshare legs at current Portland rates, which often run $12–$20 each way to PWM.

The Green Lot sits on-airport, so you use the same security checkpoint in the Main Terminal that all PWM gates feed from. That 100-foot walk means you can realistically park, lock up, and stand in the check-in line in under 5 minutes if you’re not dealing with checked bags for a large group. Build your timing around TSA wait predictions, not shuttle schedules.

Tip: For departures before 7 a.m., plan to park in the Green Lot at least 90 minutes before your flight; the $15/day rate is easier to swallow than sprinting that 100-foot stretch to the Main Terminal while boarding starts.
