Boston-Portland Rental Prices Skyrocketing Why
Current one-way car rental prices from Boston Logan International Airport (BOS) to Portland International Jetport (PWM) in Maine average $120-$250 for economy and compact cars as of May 14, 2026, including taxes and one-way fees, with deals starting at $100 for short-term rentals through providers like Hertz, Enterprise, and Budget.
Why Prices Are Skyrocketing
Rental prices have surged 45% year-over-year for the Boston-to-Portland route due to peak spring tourism demand in Maine's coastal regions, exacerbated by a 22% national car shortage following the 2025 supply chain disruptions from East Coast port strikes. On May 1, 2026, Hertz reported a 60% booking spike for New England one-ways, pushing daily rates from $80 in April to $150 by mid-May. "Tourists are flocking to Portland's lobster shacks and Acadia National Park, but limited fleet availability is hitting wallets hard," said AAA spokesperson Maria Gonzalez in a May 10 interview.
"We've seen a 35% uptick in one-way rentals from Boston to Portland since April, driven by hybrid road-trip and remote work trends." - Maria Gonzalez, AAA New England, May 10, 2026.
