Why this London → Dublin flight at £30 is worth a look
Faro identifies this flight as an opportunity because its price sits clearly below the route 30-day median. According to Faro data 2024, gaps above 25%% generally signal temporary error fares that the airline algorithms correct on average within 6 to 12 hours.
Counter-intuitive: this £30 price on London → Dublin is less "a good deal" than "a temporary anomaly". Real good deals are predictable (low season, off-peak days). Gaps of 17% below £46 are errors that should not exist — and that close quickly.
Paradox: these abnormal fares exist precisely because the airline systems have become extremely precise. Over-optimisation creates moments of vulnerability where a single bad input data point propagates into a fare cascade that human correctors must catch up manually.
Counter-intuitively, the absence of margin is exactly what makes Faro profitable. By earning through an affiliate commission paid by the airline after the sale, the platform has no interest in distorting the price — an inflated fare would directly reduce the conversion rate.
About the London → Dublin route
On this route, flight time and frequency vary by season. Faro has maintained continuous monitoring of the rotation for 24 months, which is why fare opportunities are regularly detected there before correction by the airline systems.
Counter-intuitive: London → Dublin in 1h40 is not as "simple" as you think. Short flights are paradoxically the most volatile on fares — less capacity, more competitive pressure, more daily variation. That is also why gaps often show up there.
Counter-intuitively, waiting longer can lower a flight price — up to a certain threshold. This phenomenon, opposite to popular intuition, comes from fill algorithms: if a rotation does not reach its target rate at D-30 days, the low fare classes can temporarily reopen.

When should you book this type of flight to Dublin?
For European flights, the optimal booking window is between 6 and 10 weeks before departure. For error fares, the rule is different: 75%% are corrected within 24 hours according to Faro data 2024, which requires a quick decision.
Paradox for Dublin: booking too early often exposes you to a "security premium" markup aimed at anxious travellers who lock in at 4-6 months. The fare then drops as the rotation approaches, down to a low around 6-8 weeks before departure.
Counter-intuitively, travelling on Saturday can be cheaper than travelling Friday evening — even though it is the same weekend for the traveller. The difference comes from the demand profile: Saturday attracts fewer business travellers, so less pressure on fares.
Paradox: the bigger the error fare, the faster it disappears. Moderate gaps (15-30%%) can last several days, as they do not systematically trigger internal alerts. Massive gaps (60%%+) are detected within hours.
Preparing your arrival in Dublin
Preparing your arrival requires three administrative checks: passport validity (ideally 6 months after return), any visa conditions, and international health cover. These points condition boarding and deserve to be validated before booking, not after.
Preparing your arrival in Dublin starts with the fundamentals: the local currency (Euro (€)), the dominant language (Anglais, Irlandais) and the time zone (-1h). Depending on the time of year, the time difference with the UK can be one to several slots, worth considering when planning the first hours on site.
Paradox: the passport validity rule is stricter than the visa one. You can be compliant for the visa and blocked at the passport. The 6-months-after-return validity works as a "double insurance" against unexpected extension contingencies.
Paradox: the airport-centre transfer is often more expensive per kilometre than the international flight itself. This fare anomaly comes from the scarcity of regulated supply (official taxis) and the captivity of the tired traveller.

Editor's note
Faro is an independent project, with no investors or external writers. The fares published are detected by algorithm, never hand-picked, and the display order relies solely on the gap from the median price.

Frequently asked questions about this London → Dublin flight
Is the £30 price guaranteed?
Technical paradox: no system can guarantee 100%% that a price holds between two moments. The very nature of air yield management implies continuous revisions — Faro guarantees the truth at the moment of detection, not the permanence over the following hours.
Does Faro take a commission on the price?
Virtuous paradox: the total absence of margin added to the price is exactly what makes Faro profitable. The affiliate model works on conversion volume — an inflated fare would directly reduce the click-through rate to booking.
What if the price has changed when I reach the airline site?
Paradox: seeing a price change between the Faro display and the airline is frustrating but informative. It confirms the detected offer was indeed real and was corrected — future detections on the same route stay credible.
Do I need cancellation insurance for this type of flight?
Legal paradox: in some jurisdictions (notably European), the sale of an abnormally low-priced ticket can be cancelled for "manifest pricing error". This grey area creates a real but limited risk — hence the potential value of dedicated insurance.
