Flights to Lisbon — Book & Offset Your Carbon with IMPT
Lisbon is having a moment that's lasted a decade — and for good reason. Golden light washing over pastel-coloured hills, world-class surf an hour away, pastéis de nata at every corner, and a creative scene that's drawn half of Europe's digital nomads. Delta flash sales are making it more accessible than ever from the US. Book through IMPT and offset your transatlantic carbon automatically.
Best Time to Fly to Lisbon
Lisbon has one of Europe's best climates — over 300 sunny days a year. But timing still matters for your wallet and experience.
- March–May (spring): Best overall. Warm (18–25°C), flowers blooming, fewer tourists than summer. Easter and local festivals add colour. Great flight deals.
- June–August (summer): Hot (28–35°C), long days, packed beaches. Santos Populares festival in June is incredible — sardines, street parties, fado. Peak fares.
- September–October (autumn): Still warm (20–28°C), summer crowds gone. Best time for surfing at Ericeira and Peniche. Wine harvest season. Excellent value.
- November–February (winter): Mild (10–15°C), occasional rain, but nothing brutal. Cheapest flights and accommodation. The city feels more local and less touristy.
💡 Deal alert: Delta flash sales to Lisbon have been dropping — check IMPT's flight search for current availability. TAP Air Portugal also runs frequent promotions from US gateways.
How IMPT Makes Your Flight Carbon-Negative
A round-trip flight from New York to Lisbon produces roughly 1.2 tonnes of CO₂ per passenger. From London, about 0.4 tonnes. From within Europe, it's even less. IMPT offsets all of it — regardless of origin.
When you book flights through IMPT's flight search, your journey triggers verified carbon removal. IMPT retires UN-verified carbon credits — tokenised on Ethereum, permanently auditable, and impossible to double-count.
The credits fund real projects: reforestation with named farmers and GPS-tagged trees, renewable energy, and community-led conservation. Every credit is retired on-chain with a public retire code.

Where to Stay in Lisbon
Lisbon's seven hills create distinct neighbourhoods, each with its own soul. Where you stay matters.
- Alfama: The oldest neighbourhood. Narrow medieval streets, fado music drifting from restaurants, viewpoints at every turn. The authentic Lisbon experience.
- Bairro Alto: Nightlife central. Quiet by day, alive by night. Restaurants, bars, and clubs packed into narrow streets. Best for party-goers.
- Baixa/Chiado: The elegant centre. Praça do Comércio, boutique shopping, grand cafés. Most convenient location for sightseeing.
- Príncipe Real: Upscale, trendy, leafy. Boutique hotels, brunch spots, and the botanical garden. Lisbon's hipster quarter.
- LX Factory area (Alcântara): Industrial-chic. Converted factory complex with bookshops, restaurants, and weekend markets. Creative and affordable.
Book your Lisbon hotel through IMPT and get €5 free credit, 5% back on every stay, and 1 tonne of CO₂ removed per booking — up to 10% cheaper than Booking.com.

Things to Do in Lisbon
Lisbon is a city best explored on foot (good calves required) and by tram. Here's the essential list:
- Pastéis de Belém: The original pastel de nata bakery since 1837. The queue is long but moves fast. Dust with cinnamon and powdered sugar. Nothing else compares.
- Tram 28: The famous yellow tram rattles through Alfama, Graça, and Baixa. Touristy? Yes. Worth it? Absolutely. Go early morning to avoid sardine-can conditions.
- Time Out Market: A food hall in Mercado da Ribeira with the best of Lisbon's restaurants under one roof. Seafood, wine, petiscos (Portuguese tapas). Essential.
- Surf at Costa da Caparica: 30 minutes from the city centre by ferry + bus. Kilometres of Atlantic surf beaches. Consistent waves, beach bars, and sunset sessions.
- Day trip to Sintra: 40 minutes by train. Fairytale palaces (Pena Palace, Quinta da Regaleira), misty forests, and the westernmost point of mainland Europe at Cabo da Roca.
