At Porto Airport, security deposits held on your card range from £171 with Budget or Avis to £4,709 with Hertz Dream Collection, and 27 of the 29 counters require a credit card. Only Goldcar accepts a debit card across its fleet, while Avis accepts a debit card for some cars only. The deposit and card rule for each vehicle are shown beside it in the results, so filter for a debit card before comparing prices.

If you bring your own child seat, check your airline's rules first: most carry one free, some charge.

Two main traps catch drivers out at Porto Airport: security deposits that require a credit card, and slow counter queues. Of the 29 desks at the airport, 27 reject debit cards outright, leaving travellers without a credit card stranded at the counter. Queues can also eat into your first morning: waiting at U-Save and Enterprise averages 33 minutes, while Flizzr takes just 9 minutes. At least you will not spend that wait wondering where the shuttle bus is, as every counter is located right at the airport.

Only 62% of prices at Porto Airport are full tank out, full tank back, so read the fuel line under the car before you book.

A Compact car such as a Ford Focus at Porto Airport costs around £22 a day for October 2026 and fits most small groups comfortably. It seats 5 but holds 3 bags, making it easy to steer down narrow village lanes while still fitting holiday luggage. A couple with lighter luggage can save a little by choosing a Mini like the Fiat 500 at £17 a day, while a group with extra bags will need an Intermediate like the Nissan Qashqai at £32. Automatics make up 45% of cars on offer but cost £8 more a day than manuals, while electric and hybrid models make up just 7% combined, so book them well in advance if you want one.
