Bucharest to Iasi 2026: Fly 1h, Train 6h18

Fly if you’re trying to save the day. On 18 August 2026 CFR’s fastest listed train, IR-1661, is scheduled 6 hours 18 minutes from Bucuresti Nord to Iasi over 404 km. Tarom’s OTP-IAS hop is 1 hour 10 minutes in the air on an ATR 72; Animawings lists the same hop at 50 minutes on an A220. The coach isn’t the slow cousin here: Autogari’s fastest Micedu run on 20 August 2026 is 6 hours 29 minutes. Confirm before you buy - timetables move - but the ranking holds: the plane wins the daylight, and the train and the bus fight over the same six-and-a-bit hours.

That’s the opposite of Bucharest to Cluj, where the railway is a full working day. Iasi is closer, the daytime CFR path is shorter, and a cheap 75 lei RVG seat can undercut the train. If you already know you’re heading into Iasi for the Palace of Culture and then west to the painted monasteries, pick the mode for the next two days, not for a postcard of “the Romanian train”.

The short version

Figures above are operator or official-band numbers checked in August 2026. Re-check before you travel.

Fly OTP to IAS: 50 min to 1h10

Two airlines actually fly it in 2026: Tarom on ATR 72s timed at 1 hour 10 minutes, and Animawings on A220-300s timed as tight as 50 minutes. Tarom’s RO701 is a weekday morning OTP departure, with later RO703 / RO707 filling the day; Animawings is thinner than Tarom - not a metro. Check the date with the carrier. Blue Air does not fly this. It stopped in September 2022 and went bankrupt in July 2025.

Door to door you still burn a half-day: Otopeni has no metro yet, then security, then bus 50 in Iasi. That still beats 6h18 in a seat. The catch is price. Tarom’s destination pages errored on 18 August 2026, and its “from 39 EUR” Iasi card was a 12-14 January 2026 purchase window. Don’t budget on an expired promo. Compare the date you’ll actually travel, then buy on the carrier.

If Iasi is the point of the whole trip, you can skip Bucharest entirely and land at IAS from abroad - it’s the country’s third-busiest airport, and which airport to fly into for Romania is the page for that choice. This page is the other job: you’re already in Bucharest and you need the second city.

The CFR daytime run from Gara de Nord

You’ll leave from Bucuresti Nord, not from the airport, and you arrive at Iasi station, which sits on the west side of the centre rather than 8 km out. On the 18 August 2026 list there were five CFR trains, no private operator on this snapshot:

• IC-561 06:45-13:05, 6h20, 403 km
• IR-1661 11:50-18:08, 6h18, 404 km - the fastest
• IR-1663 16:25-22:58, 6h33, 403 km
• IRN-402 19:06-02:03, 6h57, 460 km - get off in Iasi; the train keeps going toward Chisinau
• IRN-1669 22:55-05:35, 6h40, 404 km

So don’t treat a seven-hour train versus a one-hour flight as the cartoon. It isn’t. The useful daytime trains are a little over six hours, and the night seat is in the same band. Buy on bilete.cfrcalatori.ro or at the counter; InterCity and Interregio on this corridor take a seat reservation.

The money side is stabler than the airline. When CFR and the new timetable landed on 14 December 2025, the published full ticket for Bucharest-Iasi sat at about 140-160 lei Interregio and 159 lei InterCity. That full price is the transport band plus the reservation ticket (CFR’s own page is clear that the printed kilometre table does not include reservation). Online advance fares can undercut the full tariff; the live total is the one on the checkout, not a screenshot from this page.

IRN-402 at 19:06 is the Prietenia departure in our Bucharest to Chisinau guide. Get off in Iasi in the small hours, or stay on through Ungheni. The dedicated dawn arrival is IRN-1669 at 05:35, not a 02:00 drop.

Coaches from Basarab, Obor and Filaret

The bus looks slow on paper until you put it next to the train. Autogari’s 20 August 2026 board listed nine coaches - Micedu, maSSaro, Hermes, RVG Speed, Trendbus - and a page range of 75 to 150 lei. FlixBus was not on that listing.

The useful rows: fastest Micedu, 6h29, 150 lei, from Autogara IDM Basarab Kennedy to Autogara Transbus Codreanu beside Iasi station; cheapest RVG Speed, 6h59, 75 lei, from Autogara Obor, with an Otopeni call at 06:30 before the 07:15 Obor departure if you’re coming off a flight. Hermes, maSSaro and Trendbus fill the rest at 150 lei and 6h59-7h59, Trendbus from Autogara Filaret.

Like-for-like, 150 lei / 6h29 on Micedu versus about 140-160 lei / 6h18 on CFR leans train on both clock and fare. The 75 lei RVG seat is what flips “train is cheaper”, and Autogari flags variable prices, so treat 75 as a snapshot. Read the station on the ticket. Basarab, Obor and Filaret aren’t interchangeable.

When a car still earns its keep

Don’t drive this as a transfer. The railway is 403-404 km; the road follows the same corridor on DN2, with pieces of A7 opening in stages. CNAIR’s director said in July 2026 that the end-2026 aim is 397 km of motorway from Bucharest to Pascani (A3, A7, Bacau beltway). That’s a target, not an August opening, and Iasi sits beyond Pascani, so the last stretch stays national road.

A car earns the fuel and the rovinieta when Iasi is a base: the Bucovina monasteries sit two to three hours west, and buses make a poor day of them. A private driver for the A-to-B hop just buys the same six hours the train already sells. The airport last mile is a different product - that’s the next section.

Bus 50 from the airport into Iasi

IAS is about 8 km east of the centre. CTP Iasi’s own airport page is unusually clear: express bus 50 runs Gara - Piata Unirii - Targu Cucu - Airport, and back via Piata Independentei. It runs around the clock, every 30 minutes. A single ticket is 4 lei (8 lei for two), valid 120 minutes across the CTP urban network after you validate; you can buy from the driver, from the machine at the Aeroport stop, or on the 24 Pay app.

That’s the cheap last mile after the flight, and it drops you on the boulevard the city actually uses. Bolt and Uber run; a pre-booked transfer is what you want with luggage or a late arrival. The Bucharest end is a separate problem - Bucharest airport to the city covers OTP, because Otopeni touts are a worse surprise than anything in Iasi.

Pick by the clock, not by habit

If you have a lunch in Iasi, fly. Fifty minutes to 1h10 in the air plus the airport dance still leaves you a city day; 6h18 on IR-1661 does not. If you’d rather spend about 140-160 lei than an airline fare, and you don’t mind giving the day to the window, take the 11:50 IR-1661 and walk out of Iasi station toward the Palace. If a 75 lei Obor coach is actually on sale for your date, that’s the value play - just don’t assume every coach is 75 lei, because most of the 20 August board was 150.

Night people have a cleaner split than the daytime crowd: IRN-1669 at 22:55 for a 05:35 Iasi arrival, or the 19:06 if you’re connecting onward to Moldova. Drive only as the first hour of a Bucovina week. And if you’re still shaping the Romanian half of the trip, getting around Romania is the wider map; this page is just the Bucharest-Iasi stick, measured on the carriers’ own clocks in August 2026.
