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

Airline (IATA)	Base Fare (€)	Duration	Checked Bags	Booking Window
Wizz Air (W6)	62	2h 15m	20kg included	35-42 days prior
Ryanair (FR)	68	2h 30m	10kg included	30-37 days prior
easyJet (U2)	92	2h 40m	20kg included	28-35 days prior

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. Book directly on airline sites to avoid third-party fees (e.g., 15% markup on Traveloka for OTP-LIS routes in 2024).

Logistics: Airport Codes & Transfers

Lisbon’s airport code is LIS (Portela), 15 minutes from the city center. Transfer from LIS to downtown costs €4.50 on bus 30 or €12-€15 by taxi. Bucharest’s OTP airport is 25 minutes from the city center via bus 400 (€1.20) or taxi (€15-€20). Avoid flights landing at Madrid (MAD) for Lisbon trips—transfers add 90 minutes and cost €35+.

Q: What’s the cheapest airline from OTP to LIS in October 2024?

A: Wizz Air averages €79 for October 2024 departures, 21% cheaper than Ryanair’s €97. Book before September 15 to secure this rate, as October fares rise 18% after September 20.

Q: How much do checked bags cost on budget airlines?

A: Ryanair charges €23 for the first 20kg bag when booked online (€18 if added during booking), while Wizz Air includes 20kg free on all tickets. easyJet adds €30 for 20kg if purchased separately.
