DTW Airport Green Lot: Rates, Shuttle & Parking Tips 2026

The DTW Airport Green Lot is Detroit Metropolitan Wayne County Airport's most affordable on-airport parking option, charging a flat $20 per 24-hour period with no height restrictions — making it the go-to choice for long-term parkers, oversized vehicles, and budget-conscious travelers. A free shuttle connects the Green Lot to both the McNamara Terminal and the Evans Terminal (formerly North Terminal), so no matter which airline you fly, the Green Lot has you covered. For context on all DTW parking options, start with the Complete DTW Airport Parking Guide.

• Flat $20/day rate: each 24-hour period or partial period billed at $20 (per metroairport.com, verified October 2026)
• Card payment only: a 2.65% processing fee applies to every transaction
• No height limit: the Green Lot accepts all vehicle sizes, including trucks, SUVs, and vans over 8 ft 2 in
• Free shuttle to both terminals: serves the Ground Transportation Center at McNamara Terminal and Evans Terminal
• Off-site lots on Triply start at about $10/day before tax: the Detroit Metro Airport Marriott is about $10/day plus tax, Wyndham Garden Romulus about $11/day, and Valet Connections and Hampton Inn Detroit/Belleville about $12/day, all with free shuttles. Rates are for a 7-day stay booked ahead and change by date.
• No online reservation listed: the airport's parking pages do not list advance booking for the Green Lot, so plan on driving up

DTW Airport Green Lot Rates and Rules for 2026

The Green Lot charges $20 flat per 24-hour period, per official parking data published by the Wayne County Airport Authority (verified October 2026). Every additional or partial 24-hour period adds another $20. That means if you return 25 hours after you arrived, you pay $40 — not $20. There is no partial-hour pricing at the Green Lot; the clock resets every full day.

Payment is card only at the Green Lot exit. The airport adds a 2.65% card processing fee to every parking transaction. On a 7-night stay (8 billed days), that fee adds about $4.24 to your total. It's a small amount, but worth knowing before you pull up to the booth. Cash acceptance at the Green Lot is not confirmed on metroairport.com, so bring a card to avoid any issues.

The Green Lot has no vehicle height restriction. The on-airport garages — McNamara Garage and Big Blue Deck — both max out at 7 ft 0 in for standard areas, with limited van-accessible spaces up to 8 ft 2 in. The Green Lot is the right choice if you drive a full-size pickup truck, a large SUV, a camper van, or any vehicle taller than 8 ft 2 in. All long-term parking areas at DTW, including the Green Lot, offer handicap-accessible parking spaces.

The airport's parking pages do not list online reservations or advance booking for the Green Lot, so plan on driving up. If you want to confirm availability before your trip, call the 24-hour parking status hotline at (800) 642-1978. During peak travel periods such as holidays, spring break and summer weekends, the Green Lot can fill up. Calling ahead is a smart move.

One important heads-up for 2026: the $85.5 million Dingell Drive Tunnels and Roadway Rehabilitation project is ongoing through 2027. Construction may cause temporary lane closures and detours on airport access roads near the Green Lot entrance. Allow extra drive time, especially during morning and afternoon rush hours. Check current construction updates on metroairport.com before you leave home.

Searching for ways to trim your total cost? The sibling guide on Detroit Metro airport parking coupons and deals covers discount strategies at DTW, and booking an off-site lot ahead on Triply is another way to come in under the Green Lot rate.

Compare DTW off-site parking from about $10/day before tax on Triply, versus $20/day at the Green Lot.

How Does the DTW Airport Green Lot Shuttle Work?

The Green Lot shuttle is free and connects the lot to the Ground Transportation Center at both McNamara Terminal and Evans Terminal. You do not need to pay separately for the ride, since it is included with your parking.

The Wayne County Airport Authority does not publish a specific shuttle frequency on its parking pages, so we cannot quote an exact number of minutes between pickups. Traveler reports suggest the shuttle runs regularly, but you should plan conservatively, especially early in the morning, late at night, or on off-peak days. The airport's free shuttle also connects McNamara Terminal, Evans Terminal and the on-airport parking areas, so you may share the ride with guests from other lots.

On your outbound trip, follow signs for the Green Lot when entering the airport campus. After you park, look for the clearly marked shuttle stop near the lot. On your return trip, head to the Ground Transportation Center inside whichever terminal you land in. At McNamara Terminal, the Ground Transportation Center is on the lower level near baggage claim. At Evans Terminal, follow signs for Ground Transportation after collecting your bags. The shuttle will bring you back to the Green Lot.

Because McNamara Terminal and Evans Terminal are not connected by a walkway, the free airport shuttle is also the correct way to get between the two terminals if you ever need to switch. Do not attempt to walk between them — the distance makes it impractical, and there is no pedestrian path.

If you want the most frequent shuttle among the lots Triply sells, Valet Connections runs every 10 to 15 minutes, 24 hours a day, at about $12/day, less than the Green Lot's $20. It has a 2-day minimum, and part of the price is paid at the lot. More on that comparison below.

Is There a Blue Lot at DTW?

There is no parking facility called the "Blue Lot" at Detroit Metro Airport. The name that causes confusion is the Big Blue Deck — a multi-level parking garage that serves the Evans Terminal (the terminal used by Alaska, American, Frontier, JetBlue, Lufthansa, Southwest, Spirit, Sun Country, and United Airlines).

The Big Blue Deck is a covered, on-airport garage — not an open surface lot like the Green Lot. Its long-term rate is $23/day, and short-term parking maxes out at $43 for a 10–24 hour period. If you fly a non-Delta airline out of Evans Terminal, the Big Blue Deck is the closest covered option. The Green Lot, by contrast, serves both terminals via shuttle and costs $3 less per day than Big Blue Deck long-term.

Here's a quick summary of the naming to keep straight:

• Green Lot: open surface economy lot, $20/day flat, no height limit, free shuttle to both terminals
• Big Blue Deck (long-term): covered garage at Evans Terminal, $23/day, 7 ft height limit (limited 8 ft 2 in spaces on Level 1)
• Big Blue Deck (short-term): same garage, up to $43 for 10 to 24 hours
• McNamara Garage (long-term): covered garage at McNamara Terminal, $32/day, serves Delta and SkyTeam airlines
• McNamara Garage (short-term): same garage, up to $44 for 10 to 24 hours
• McNamara Valet: available at McNamara Terminal only, $51/day maximum

How Much Does a Week at the DTW Airport Green Lot Cost?

A 7-night trip means 8 billing periods at the Green Lot, because your return day counts as a new partial period. At $20/day, that's $160 total before the card fee. Add the 2.65% surcharge and your total comes to roughly $164.24.

For comparison, here's what the same 7-night stay (8 billed days) costs at the Green Lot, the long-term garages and the four off-site lots bookable on Triply. On-airport parking is paid at the airport, not through Triply. Triply totals are the real checkout totals, including fees and tax.

Over the same 7-night window, the four Triply lots come to $92.93 to $104.54, about $55 to $67 less than the Green Lot's $160 before the card fee. The Marriott has the lowest base rate (about $10/day), but about 27% tax is added, so its $104.54 checkout is the highest of the four. Wyndham Garden Romulus has the lowest total at $92.93. Valet Connections, with the most frequent shuttle (every 10 to 15 minutes), comes to $94.00, and part of that is paid at the lot.

When Does an Off-Site Lot Beat the DTW Airport Green Lot?

For multi-day trips, the four off-site lots on Triply cost less than the DTW Airport Green Lot, sometimes by a wide margin. The Green Lot's $20/day rate is the cheapest option on-airport, but the off-site lots come in at about $8 to $10 less per day (the Marriott's rate is before tax), and all four include free shuttles. Two have minimum stays: Valet Connections needs 2 days and Hampton Inn Detroit/Belleville needs 3.

Here's when the Green Lot still makes sense:

• Your vehicle is taller than 8 ft 2 in, so the garages can't accommodate it. Valet Connections and Hampton Inn Detroit/Belleville list no extra charge for full-size vans, pickup trucks and large SUVs, but confirm height limits with the lot
• You're arriving at the airport with no reservation
• Your trip is 1 day: Valet Connections (2-day minimum) and Hampton Inn Detroit/Belleville (3-day minimum) are out, so the Green Lot's $20 flat rate is competitive for a very short stay
• You prefer on-airport peace of mind, since the lot is operated directly by the Wayne County Airport Authority

And here's when an off-site lot wins:

• Multi-day trip: savings compound quickly at about $8 to $10 less per day (the Marriott's rate is before tax)
• You want a confirmed reservation: all four Triply lots offer online booking and free cancellation with a full refund up to 24 hours before check-in
• You need frequent shuttle service: Valet Connections runs every 10 to 15 minutes, versus an unpublished Green Lot frequency
• You want added amenities: the Marriott lot lists a restaurant, a 24/7 front desk and in-and-out privileges
• You're flying from Evans Terminal on Southwest, American, or United: the Big Blue Deck is closer, but all four Triply lots cost less than its $23/day long-term rate

The research on what travelers look for when choosing an airport parking lot shows that shuttle frequency and free cancellation rank as top priorities. Every lot Triply sells at DTW has a free shuttle and free cancellation with a full refund up to 24 hours before check-in.

Before you drive to the airport, check real-time traffic on Waze — especially relevant in 2026 given the ongoing Dingell Drive construction near the airport entrance.

Step-by-Step: First-Time DTW Airport Green Lot Guide

No competitor article walks you through the full Green Lot experience. Here's exactly what to expect from arrival to terminal.

1. Enter via Dingell Drive — Follow signs for long-term/economy parking when approaching the airport campus off I-94 or I-275. The Green Lot is signed from the main airport roadways.
2. Take a ticket at the entry barrier — The lot uses a ticketed system. Keep your ticket — you'll need it to exit.
3. Park and note your row and space — The lot is open-air with no height restrictions. Take a photo of the nearest sign or row marker before walking to the shuttle stop.
4. Find the shuttle stop — Look for the marked shuttle pickup area near the lot entrance. The free shuttle picks you up and takes you to the Ground Transportation Center at both terminals.
5. Tell the driver your terminal — McNamara Terminal (Delta, Air France, KLM, Korean Air, WestJet) or Evans Terminal (Alaska, American, Southwest, United, and others). The shuttle serves both.
6. On return, go to Ground Transportation — After baggage claim, follow signs for Ground Transportation or Shuttle Buses. The Green Lot shuttle picks up at the Ground Transportation Center.
7. Pay at the exit booth — Card only, 2.65% fee applies. Have your ticket ready.

For international arrivals at McNamara Terminal, clear customs and follow signs for baggage claim, then proceed to Ground Transportation. The process is the same — the shuttle meets you at the curb level. If you have TSA PreCheck, the TSA PreCheck enrollment program can also shave meaningful time off security on the way out, which is especially helpful if you're cutting it close after a long drive from the Green Lot shuttle.

Green Lot vs. On-Airport Garages: Height, Coverage, and Convenience

The most practical difference between the Green Lot and the on-airport garages is vehicle height. McNamara Garage and Big Blue Deck both limit standard parking to 7 ft 0 in. Van-accessible spaces extend to 8 ft 2 in — McNamara on Level 2 near the B elevators, and Big Blue Deck on Level 1 zones A and B. Anything taller belongs in the Green Lot.

The second difference is covered vs. open-air. The garages protect your vehicle from Michigan winters: snow, ice, and sub-zero temperatures. The Green Lot is exposed to the elements. If you're parking through January or February, the McNamara Garage and Big Blue Deck are the only covered options at DTW, and none of the four lots Triply sells is covered either. That said, many Michigan travelers park in the Green Lot year-round without issue. Just expect to clear snow off your windshield when you return.

The third difference is terminal proximity. The McNamara Garage connects directly to McNamara Terminal — no shuttle needed. The Big Blue Deck connects directly to Evans Terminal. The Green Lot requires the free shuttle for both. If you're a Delta frequent flyer who values walking straight from your car to the Delta Sky Club, the McNamara Garage at $32/day earns that convenience. For everyone else, the Green Lot shuttle trade-off at $20/day makes clear financial sense.

Parking at DTW During Peak Travel and Holidays

The Green Lot can reach capacity during the busiest travel days of the year. Detroit Metro is a major Delta hub, and peak periods see heavy demand across all parking facilities. Based on typical airport parking patterns, the highest-risk fill times at the DTW Airport Green Lot are:

• Thanksgiving week (Tuesday–Wednesday before, Sunday after)
• Christmas and New Year's (December 22–26 and December 30–January 2)
• Memorial Day, July 4th, and Labor Day weekends
• Spring break (typically mid-March through mid-April)
• Major Detroit-area events — auto shows, sporting playoffs, large conventions

The airport does not publish real-time Green Lot occupancy online. Your best option is to call the 24-hour hotline at (800) 642-1978 the day before you leave. If the Green Lot is at or near capacity, consider booking an off-site lot through Triply in advance. All four Triply lots offer free cancellation with a full refund up to 24 hours before check-in, so you can reserve a backup and cancel in time if you end up using the Green Lot.

Should You Book the DTW Airport Green Lot in Advance?

The airport's parking pages do not list advance online reservations for the Green Lot, so plan on driving up and call (800) 642-1978 for status on busy days. If you want a space reserved before you leave home, an off-site lot on Triply lets you book online.

Off-site lots on Triply let you reserve online before you leave home, and all four include free cancellation with a full refund up to 24 hours before check-in. For trips of any significant length, such as a week of vacation or a business trip over several nights, booking at about $10 to $12/day (the Marriott's rate is before about 27% tax) puts you well under the Green Lot's $20/day. Keep the minimum stays in mind: 2 days at Valet Connections and 3 days at Hampton Inn Detroit/Belleville.

According to the FAA's aviation statistics, DTW consistently ranks among the nation's busiest airports — which means parking pressure is real during peak periods. Planning ahead isn't overcaution; it's basic preparation for a major hub.
