At Boston Airport, security deposits range from $200 with Budget and Sixt to $299 with Avis, and 4 of the 9 desks accept a debit card. Another 3 desks accept a debit card for some cars only, while 2 counters require a credit card. Filter for a debit card before comparing prices so you only see vehicles you can collect. Any optional extras charged at the desk are listed under each car.

Two main traps catch drivers out at Boston Airport: desks that refuse debit cards and long waits at the counter. While all 9 counters are located at the airport, 2 desks refuse debit cards completely and 3 take them only for select models. Desk waits also vary wildly, stretching up to 24 minutes at National compared to just 2 minutes at Budget or Dollar. Spending 24 minutes in line is a dull way to discover your debit card is no good.

For comfort leaving the city, pick an Intermediate car like the Volkswagen Jetta at Boston Airport, which costs around $88 a day in October 2026. It seats 5 people and holds 4 bags, whereas stepping down to a Compact like the Nissan Versa costs $86 but drops luggage space to 3 bags. Stepping up to a Fullsize like the Chevrolet Malibu costs $105 a day and seats 6. Every car offered is automatic, while electric models make up only 1% of the fleet, so securing one without booking well ahead is rare.
