Estimate airport parking costs for a trip.
Airport parking has a structure that rewards long stays and punishes short ones: an entry or first-day surcharge is spread across however many days you are away, so the effective daily rate on a two-day trip is much higher than on a two-week one. Prepaid online booking typically knocks 10 to 20% off the gate rate, which is the easiest saving available. The comparison that matters is against a rideshare round trip, which is a fixed cost regardless of trip length — so there is always a crossover point. Below that number of days, take the car service; above it, park.
Airport Parking Estimate
Gross = days x daily rate + surcharge; total = gross x (1 - prepaid discount%); effective daily = total / days; break-even days = rideshare cost / effective daily
For trips under three or four days a rideshare usually wins because parking accrues daily while the car service is a fixed cost. For a week or more, parking is generally cheaper.
Often yes on long trips — off-site lots run at a third to a half of on-terminal rates. Budget 20-30 minutes each way for the shuttle, and check the frequency for early departures.
