How Many Hours Is the Flight from Portugal to São Tomé?

All the schedules and timings below refer specifically to the nonstop Lisbon–São Tomé route. If you are flying in from outside Portugal, add the time needed to reach Lisbon first, since this is currently the only city with a direct connection to São Tomé.

The direct flight from Lisbon to São Tomé takes, on average, 6h30 to 6h45, with no stopover. Two airlines operate this route — TAP Air Portugal and STP Airways — and choosing between them changes how your first and last day of the trip actually feel, far more than the small difference in flight time.

TAP Air Portugal or STP Airways: which one fits you best?

TAP Air Portugal departs Lisbon in the morning and lands in São Tomé in the late afternoon or evening. In practice, day one of the trip is a travel day — you reach the hotel at night, have dinner, and go to bed at a normal hour. It's the more comfortable option for travellers who don't like losing sleep or arriving exhausted somewhere new.

STP Airways does the opposite: the flight leaves Lisbon at five past midnight, flies overnight, and lands in São Tomé quite early in the morning. If you can handle a night without sleep, you get a full day to start enjoying the trip right away. The trade-off shows up on the way back: the return flight always departs in the morning, meaning a wake-up call around 4am for check-in — so with STP, it's the last day that becomes a travel day.

In short: with TAP you lose day one; with STP you lose the last day, and with an early alarm attached. It's a fairly even trade-off, and the right choice mostly comes down to how well you cope with a poor night's sleep.

Flight frequency

TAP Air Portugal flies this route on Wednesdays, Fridays, Saturdays and Sundays. STP Airways only flies on Saturdays. Depending on the dates you already have fixed, that can settle the choice for you — always worth checking current frequency before finalising the rest of the trip.

Baggage: another difference worth knowing

On its basic fare, TAP includes standard checked baggage, with the usual 23kg limit. STP Airways typically allows up to 2 bags of 30kg each — a real advantage if you're travelling with diving gear, a surfboard, or simply like bringing things back from the archipelago.

How early to get to the airport

As a long-haul flight with checked baggage, the recommended minimum is 3 hours before departure. For STP Airways' 00:05 departure, it's worth keeping that same margin even though the airport is quiet at that hour — check-in still closes a set time before boarding.

Exact distance and duration

The Lisbon–São Tomé route covers around 4,560 km, with an average flight time of 6h30 to 6h45 depending on conditions.
