Firefly is a budget brand at Lisbon Airport (LIS) – part of the Hertz family – with eye-catching low headline prices but a mixed reputation for deposit holds, fuel policy and add-on pressure (Trustpilot around 2.0/5). It can be cheap if you read the terms carefully, but Lisbon's top-rated value operators often beat it with less hassle. Economy cars at Lisbon start around €12–18/day ($13–$20). Note the Lisbon area still has tolls (A5, bridges, ring roads). This guide covers Firefly in Lisbon honestly, the real prices, the better alternatives, and the traps to avoid.

Firefly is the budget arm of the Hertz family at Lisbon – cheap headline prices, but read the terms.
Lisbon Airport (LIS) is a large, competitive market. But with budget brands like Firefly, the cheapest rate rarely survives the counter once extras are added. Expect roughly:
Average Daily Rates at Lisbon Airport by Season
Booked 4–6 weeks in advance, prices in EUR
| Season | Manual Economy | Manual Compact | Automatic Compact |
|---|---|---|---|
| Low (Nov–Feb) | €12–18 | €15–24 | €26–42 |
| Shoulder (Mar–May, Oct) | €18–30 | €24–38 | €38–55 |
| Peak (Jun–Sep) | €32–48 | €38–58 | €55–85 |
Firefly's headline rate is among the lowest – but factor in deposit, insurance and fuel policy before booking.
Firefly is the budget arm of the Hertz family (with Dollar and Thrifty), so it shares the group's reservation system and is handled through the Hertz operation at Lisbon Airport.
Firefly's Trustpilot score sits around 2.0/5, with recurring complaints about large deposit holds, strict fuel policy (often prepay-a-tank), and pressure to buy extras at the counter. If you book Firefly, read the fuel and deposit terms line by line, decline cover you don't want, and document the car carefully.
Friendly service and below-average prices – far less hassle than the budget chains for a similar (or lower) price.
A well-rated Portuguese brand that often undercuts the global chains with clearer terms.
The strongest international brand at Lisbon for a newer fleet and a real terminal desk – far better reviews than the budget arms.
A dependable major with a broad fleet and clearer terms than the budget brands.
The subject of this guide. Low rates but a 2.0/5 Trustpilot average, with recurring deposit, fuel-policy and upsell complaints. Viable only if you read every term and decline extras.
Aggressive upsells, fuel and damage disputes, and one of the lowest Trustpilot scores in the industry (1.6/5).
Cheap online but notorious for strict fuel rules, toll fees and excess disputes at return.
Basic CDW with an excess of €1,000–€1,800 (budget brands often block higher deposits). Tyres, glass and underbody usually excluded.
Super CDW to zero the excess is €15–25/day – budget-brand counters push it hard.
Standalone excess insurance (€4–7/day) bought before you travel covers the excluded items and refunds any excess charged – especially worthwhile with a budget brand.
