Is there a direct flight from Dublin to Iași?
Yes—Ryanair operates a direct service between Dublin (DUB) and Iași (IAS). The flight lasts about 3 hours 40 minutes and covers a distance of roughly 1,547 miles, according to flight data aggregator FlightsFrom.com. KAYAK reports these flights operate four days a week: Monday, Wednesday, Saturday, Sunday. No other airline currently offers a direct nonstop connection on this route.
Ryanair direct service
- Ryanair is the primary carrier for nonstop Dublin–Iași flights.
- Budget airline Ryanair lists one-way fares from as low as €26.82 (approx. $29) on select dates.
- Travel search engine Skyscanner shows similar starting prices — $29 or $42 including taxes on certain days.
Flight duration and schedule
According to KAYAK’s route analysis, the direct flight takes roughly 3 hours 40 minutes. Thursday is the day with the fewest delays, and Ryanair’s punctuality on this route stands at only 12% of flights delayed in the past year.
The implication: for speed and simplicity, the direct flight is unmatched.
Which airlines fly from Dublin to Iași?
Beyond Ryanair’s nonstop, a small number of carriers connect Dublin to Iași via intermediate hubs. Here’s how they compare.
Ryanair
- Nonstop DUB–IAS, 4 flights per week (Mon, Wed, Sat, Sun) per KAYAK.
- Ryanair’s official site shows one-way fares from €26.82.
HiSky Europe
- FlightsFrom.com notes that HiSky Europe also operates a direct Dublin–Iași service, offering an alternative to Ryanair.
Other connecting airlines
If you’re willing to connect, major European carriers serve nearby airports: KLM, Air France, Lufthansa, Austrian Airlines, and Tarom — all flying via their respective hubs (Amsterdam, Paris, Frankfurt, Vienna, Bucharest). These are generally more expensive and longer but may be useful if Ryanair’s schedule doesn’t fit.
Ryanair and HiSky cover direct needs. Connecting flights from full-service carriers can cost 2–3 times more but offer more flexibility.
The pattern: direct is cheapest and fastest, connections offer flexibility at a premium.
How much do flights from Dublin to Iași cost?
Prices vary sharply by season, booking lead time, and airline. We looked at five major aggregators to get a reliable picture.
| Price metric | Amount | Source | Source type |
|---|---|---|---|
| Cheapest one-way (Ryanair) | €26.82 / $29 | Ryanair official site | Tier 1 |
| Cheapest one-way (Skyscanner) | $29 | Skyscanner | Tier 2 |
| Average round-trip (Expedia) | $194 (≈€179) | Expedia | Tier 2 |
| Cheapest month (round-trip) | $113 (≈€104) – January | KAYAK | Tier 2 |
| Most expensive months | December $576, August $504 | KAYAK | Tier 2 |
| One-way average (eDreams) | $265 | eDreams | Tier 2 |
The pattern: buying 4–6 weeks ahead and traveling in late spring or early fall keeps fares low. Avoid summer holiday weeks and December.
A family of four flying in August could pay €1,500 more than the same trip in September. The booking window is your biggest lever.
The catch: fare swings can be extreme, so lock in a deal as soon as you see it.
When is the best time to book Dublin to Iași flights?
Timing is everything. Here’s what the data says.
- Booking window: Ryanair recommends planning ahead for the lowest fares. Third-party data from KAYAK suggests 4–6 weeks in advance is the sweet spot.
- Seasonal trends: KAYAK’s pricing data shows January as the cheapest month for round-trips ($113 avg), followed by September and May. December and August are highest.
- Day of week: Thursday has the fewest delays; weekend flights may cost slightly more.
Dynamic pricing means a fare can jump 40% overnight. If you see a sub-€30 one-way on Ryanair for your dates, grab it—don’t wait for the “perfect” day.
What this means: timing is your single biggest lever for savings.
Are there alternative airports near Iași?
If direct Dublin–Iași doesn’t work, two other Romanian airports offer realistic fallback options:
- Bacău Airport (BCM) — about 100 km from Iași. FlightsFrom.com notes HiSky Europe (formerly Dan Air) flies Dublin–Bacău. Be aware that HiSky’s route schedule may change; check current availability.
- Suceava Airport (SCV) — roughly 140 km north of Iași. No direct flights from Dublin; requires a connection via Bucharest.
- Bucharest Airports (OTP, BBU) — 600+ km from Iași but served by multiple airlines from Dublin (Aer Lingus, Ryanair, Wizz Air, etc.). You’d then take a domestic flight or train to Iași.
Bacău is the closest real alternative — a direct flight from Dublin lands you just an hour’s drive from Iași. But HiSky’s long-term presence on the route is uncertain.
The pattern: Bacău gives you a direct option close to Iași, while the others require extra time and cost.
Comparison: Direct vs. Indirect Options
Five criteria separate the routes. Here’s how they stack up.
| Criterion | Ryanair Direct (IAS) | HiSky (Bacău) | Connecting via Bucharest |
|---|---|---|---|
| Travel time (incl. transfer) | 3h 40m | ~5h (flight + drive) | 5–7h+ |
| Typical one-way price | €27 – €80 | €40 – €100 | €100 – €250 |
| Frequency | 4x/week | Limited (check HiSky) | Daily via multiple airlines |
| Booking confidence | High (Ryanair stable) | Medium (schedule changes possible) | High |
| Luggage allowance | Ryanair standard | HiSky standard | Varies by carrier (often inclusive) |
The pattern: Ryanair direct is the cheapest and fastest. HiSky is a decent secondary when Ryanair is sold out. Connecting via Bucharest trades money for schedule flexibility.
The implication: choose based on your priorities – cost, time, or flexibility.

Summary
The Dublin–Iași flight market is dominated by one low-cost carrier offering direct flights at genuinely low prices — if you time it right. Ryanair’s sub-€30 one-way fares are real, but they vanish quickly. For the Irish traveller heading to Iași, the choice is straightforward: book Ryanair 4–6 weeks ahead, fly in January or early fall, and avoid peak holiday periods. If Ryanair doesn’t suit, HiSky via Bacău is a viable second option, but its future remains uncertain. For the Romanian visitor returning home, the same strategy applies — if you plan ahead, you can save hundreds of euros.
