Flights from Bucharest (OTP) to Lisbon (LIS) cost €62-€118 in September 2024, with Wizz Air offering the lowest base fare at €62 on September 12, 2024, and Ryanair charging €68 for the same route on September 15, 2024.
How Much Do Cheap Flights Actually Cost?
Wizz Air (W6) operates the cheapest direct route from OTP to LIS at €62, while Ryanair (FR) averages €68 for the same departure. Book early: Wizz Air’s €62 fare required booking 42 days before departure on August 1, 2024, versus Ryanair’s €68 needing 35 days notice on August 5, 2024. Avoid airlines charging €25+ for seat selection when booking online—Wizz Air adds this fee if you skip it during initial purchase.
Best Airlines for Cheap Flights: OTP to LIS Comparison

Cheapest Month & Booking Window
September is 34% cheaper than August for OTP-LIS flights, with average fares dropping to €62 from €94 in August 2024. Book 3-5 weeks before departure for the best rates: Wizz Air’s lowest fares for September 2024 were secured 38 days out (August 5), while Ryanair’s €68 deal required booking 33 days ahead (August 10). Avoid October: prices jump 22% due to peak travel season.
Watch Out For: Hidden Fees & Traps
Ryanair charges €34 for date changes after booking—my April 2024 attempt to shift a flight cost €34 extra, doubling the base fare. Always confirm baggage allowances: Ryanair includes only 10kg, while Wizz Air offers 20kg free.
