If you've ever circled an airport terminal hunting for parking while your departure clock ticks down, The Parking Spot offers a decent workaround: off-airport lots with a shuttle to the terminal. The chain has grown well past its East Coast roots — it now runs more than 70 locations serving over 45 airports across the United States, and it has picked up a loyal following for being straightforward and reliable.

The setup is simple. You reserve a space online or through the app ahead of your trip, so the price is locked in before you leave home. On travel day, you park in the secure lot rather than fighting terminal traffic, then ride the company's signature yellow, polka-dot shuttle to your terminal. Extras include car wash and detailing services while you're away, and on the return leg the app lets you track the shuttle in real time so you're not standing around guessing when the next one arrives.

On the savings front, there's a seasonal code worth grabbing: FALL10 knocks 10% or more off reservations that begin by November 15 — handy if you're squeezing in a trip before the holiday rush. Signing up for the company's email list gets new users 10% off their first booking, plus rotating promo codes worth 10-20% in select cities. Right now those city deals cover Austin, Denver, Columbus, Houston and Salt Lake City.

There are also standing discounts that many travellers miss. Active-duty military, veterans and airline crew members can all get 25% off a reservation when booking through a Spot Club account — crew just need to upload a photo of their work badge, and military travellers must show proof of affiliation. Note the fine print: the 25% deal doesn't apply to Basic parking reservations and can't be stacked with other offers.

If a code refuses to work at checkout, start with the basics: typos, stray spaces and wrong capitalisation are the usual culprits, followed by expired codes or ones restricted to certain locations. If the code looks fine, clearing your browser's cache and cookies or switching devices often fixes it. Failing that, customer service can sort it out.

For anyone driving to the airport a few times a year, the maths is easy: even the entry-level 10% email discount pays for itself on a week-long trip, and frequent parkers can stack the loyalty programme with crew or military rates for real savings.
