Airport Car Rental: What to Do at the Counter (and What to Refuse)
By Aqui Tem Achadinhos Editorial · Updated September 20, 2026
The rental counter is designed to sell extras. Not maliciously — it is simply the highest-margin moment in the transaction. Knowing the sequence protects your money and your deposit.
Before you get to the counter
Book online in advance. Walk-up rates are the highest of any channel.
Read the total, not the daily rate, including mandatory insurance and fees.
Check your own insurance. Credit cards and travel policies often cover part of what the counter will try to sell you.
Screenshot your booking including the confirmation number, in case of discrepancies.
At the counter: the four questions
"What is the total including all mandatory charges?" — forces the real number out early.
"Which of these are optional?" — separates insurance and extras from required fees.
"What is the fuel policy?" — full-to-full is the one you want.
"What is the deposit hold?" — a credit card hold, not a charge, but it affects your available limit.
Decline politely and firmly. "I'm covered already, thank you" ends most upsell attempts. Repeating it calmly works better than arguing about terms.
The inspection that protects your deposit
Film a single continuous video walking around the car — no cuts. Much stronger evidence than separate photos.
Capture the fuel gauge and odometer in frame with the dashboard visible.
Photograph existing damage and confirm it is on the condition report.
Check the spare and tools exist.
Test lights, wipers and AC in the lot, not on the road.
Record the same walkaround at return, with the fuel gauge and mileage — and keep both files.
⚠️ The extras that inflate the bill
Toll transponder convenience fees charged per rental day, including days with no tolls.
Additional driver fees — but adding a driver properly is cheaper than voiding your coverage.
Prepaid fuel priced above local pump prices, with no refund for unused fuel.
One-way drop fees that can exceed the rental itself.
