To save money on parking at Boston Logan Airport (BOS) in 2026, the most effective strategy is to use the Economy Parking Garage and book an Advance Parking Reservation. If you reserve your spot at least 24 hours in advance via the Massport website, you can often secure a rate of $29 per day, which is significantly cheaper than the drive-up rate of $37+. For even deeper savings, consider off-site parking lots located in Revere, East Boston, or Chelsea (such as PreFlight or Park 'N Fly); these facilities often offer rates as low as $18 to $22 per day and provide free 24/7 shuttles to all terminals. Another popular "hack" is the Logan Express bus service; instead of parking at the airport, you can park for just $7 to $9 per day at suburban terminals in Framingham, Braintree, Woburn, or Peabody and take the $9 shuttle directly to your terminal. Finally, if you drive an electric or hybrid vehicle, look for the designated "Clean Air" parking spots in the Central and Economy garages—while the parking fee is the same, these prime spots can save you time and occasionally offer free charging.
