If you’re planning a trip through Shannon Airport and wondering whether public transport is a realistic option, the short answer is yes — and it’s simpler than you might think. Three direct bus routes (343, 51, and X51) connect the airport with Limerick and Galway, with the 343 running roughly every 30 minutes during peak times.
Bus routes to Shannon Airport: 3 direct (343, 51, X51) · Route 343 frequency: Every 30-60 minutes · Route 101 serves Shannon Airport: No · Route 343 24-hour service: No · Average taxi fare Limerick to Shannon: €35-€50

Shannon Airport has solid bus connections on the Limerick corridor, but the lack of 24-hour service means late-night arrivals still rely on taxis — a clear trade-off for budget travelers.
Key facts at a glance
| Main bus operator | Bus Éireann / Expressway |
| Routes serving Shannon Airport | 343 (Limerick), 51 (Galway-Limerick), X51 (Galway-Limerick express) |
| Average journey time from Limerick | 40 minutes |
| Average journey time from Galway | 80 minutes |
| Route 343 frequency | Every 30-60 min, 7 days a week |
| 24-hour bus service available | No — last buses around 11 PM |
The table shows a clear pattern: Route 343 is the most frequent option, but none of the routes run overnight, which is the critical limitation for late travelers.
If you’re catching a red-eye or arriving after 11 PM, the bus won’t help — budget for a taxi or pre-book a transfer.
Is there a bus to Shannon Airport?
Yes — and with three distinct routes covering both the Limerick and Galway corridors, the airport is well connected by public transport. The main operator is Bus Éireann (Ireland’s national bus service), which runs the highest-frequency direct services to Shannon Airport.
Which bus routes serve Shannon Airport?
- Route 343: Limerick (Colbert Station) → Bunratty → Shannon Airport → Ennis. 31 stops, journey time about 40 minutes from Limerick. Operates every 30–60 minutes daily (Bus Éireann Route 343 page).
- Route 51: Galway → Shannon Airport → Limerick. Longer corridor, typically every 1–2 hours (Bus Éireann Expressway, intercity coach service).
- Route X51: Express version of Route 51 with fewer stops, also serving the airport (Bus Éireann Expressway).
What is the main bus operator?
Bus Éireann (Ireland’s national bus operator) runs both the local Route 343 and the Expressway services. They state they “run the highest frequency direct services to & from Shannon Airport.” Tickets can be bought on board, online, or via the Bus Éireann app.
How much is the 343 bus from Limerick to Shannon Airport?
The fare depends on whether you pay with cash, a Leap Card, or a prepaid ticket.
What is the exact fare for route 343?
- Adult single: approximately €5–€8. Rome2Rio (travel fare aggregator) lists starting fares around €11, but official Bus Éireann pricing for the 343 short hop is lower — expect about €6–€7 for a cash single between Limerick and Shannon Airport.
- Return ticket: roughly €10–€14 depending on exact stops.
- Leap Card: discounted fares; a single tap typically costs €2–€3 less than cash (Bus Éireann Leap Card info).
Are there return or student discounts?
Yes — Bus Éireann (student discount programme) offers up to 50% off with a valid Student Leap Card. Weekend returns and family tickets are also available on some services. For Expressway routes (51/X51), advance online booking can reduce the fare significantly (Bus Éireann Expressway).
How often is the 343 bus from Limerick to Shannon Airport?

- Sunday: every 60 minutes (Moovit).
What about evenings and weekends?
First departure from Limerick Colbert Station is 05:00, with the last bus leaving around 23:00 (BusTimes.org, crowd-sourced bus schedule aggregator). Route 343 is not a 24-hour service, despite some third-party listings suggesting otherwise — official Bus Éireann and Airport sources confirm no overnight operation.
Is there a bus from Limerick train station to Shannon Airport?
Yes — and it’s a short walk to the stop.
Which bus stop is nearest to Limerick train station?
Route 343 departs from Limerick Bus Station (Parnell Street), which is approximately a 5-minute walk from Colbert Railway Station. The same stop is used for Expressway services (Bus Éireann Route 343 page).

The direct bus journey from Limerick to Shannon Airport takes about 40 minutes — roughly the same as a taxi for a fraction of the price (Shannon Airport official bus page). The 53-minute figure from third-party apps (Moovit) includes all stops.
Does the 101 bus go to Shannon Airport?
No — this is a common confusion that needs clearing up.
What route does the 101 bus serve?
Route 101 runs from Dublin to Drogheda via Dublin Airport — it has nothing to do with Shannon Airport (Bus Éireann Route 101 timetable).
How is it different from route 343?
Route 343 is the dedicated Limerick–Shannon corridor, while Route 101 operates on the eastern seaboard. The only overlap is that both are operated by Bus Éireann, but their stops, direction, and purpose are completely separate. If you’re looking for Shannon Airport, always look for routes 343, 51, or X51 (Shannon Airport official bus page).
Specifications comparison: Shannon Airport bus routes
Six key dimensions, one pattern: Route 343 is the local workhorse, while the Expressway routes offer faster long-distance links.
| Attribute | Route 343 | Route 51 | Route X51 |
|---|---|---|---|
| Operator | Bus Éireann | Bus Éireann Expressway | Bus Éireann Expressway |
| Peak frequency | 20–30 min | 60–90 min | 60–120 min |
| Off-peak frequency | 30–60 min | 90–120 min | 90–120 min |
| Fare adult single | €5–€8 | €10–€15 | €10–€15 |
| Journey time (Limerick to Airport) | 40 min | — | — |
| Journey time (Galway to Airport) | — | 90 min | 75 min |
| Last departure | ~23:00 | ~21:00 | ~21:00 |
| 24-hour service | No | No | No |
The pattern is clear: none of the three routes operate overnight, so every passenger faces the same timing constraint regardless of which route they choose.

Summary
Shannon Airport’s bus network is reliable and affordable for most travelers, but it’s not a 24-hour operation. Route 343 covers the Limerick corridor with frequent daytime departures, while Expressway routes 51 and X51 link Galway. The key trade-off: you save €25–€40 compared to a taxi, but you lose flexibility after 11 PM and on Sundays. For travelers from Limerick, the choice is clear: the bus offers a reliable, cost-effective option if your flight timing aligns with the 343 schedule. For those coming from Galway, the Expressway X51 is a comfortable alternative. Either way, Shannon Airport’s bus connections make car-free travel entirely feasible — but passengers arriving late must plan for a taxi as their only option.
For those driving to the terminal, comparing Shannon Airport car parking options can help you decide whether to take the bus or park on-site.
