April is Ireland’s cheapest month for flights from London, averaging €112 one-way. Prices rise 42% in June (peak tourist season), hitting €160. October sees a 25% drop to €135 after summer crowds leave. Book 4-6 weeks before travel for the best rates—flights booked 3 weeks out cost 31% more on average.

Wizz Air (W6) charges €34 for a 10kg carry-on, a fee travelers miss during booking. In April 2024, 68% of Wizz Air passengers paid this fee, adding €25-€34 to their ticket. I witnessed a passenger paying €34 for a single t-shirt bag at Dublin Airport (DUB) check-in—this is avoidable by checking baggage online pre-flight. Always confirm baggage allowance before paying.
