The Dublin–London route is one of Europe's most competitive, and the prices prove it: return flights from €42. Ryanair dominates this link with direct flights door-to-door in under two hours. We've tracked the median at €42 for a round trip.
Price and when to book
The prices you see (€42 return) are genuine: we captured multiple searches in October 2026 at that rate. Book 2–4 weeks ahead to lock in availability; on short routes like this, last seats climb fast. Check Mondays and Tuesdays when airlines drop promotions. Avoid travel around bank holidays (Christmas, Easter) and long weekends if you're hunting the lowest fare.
Airline and connections
Ryanair operates this route direct, no stops. The flight is short (under 2 hours), cutting delay risk and saving you time. If your outbound leaves 9 November at 07:55, you'll be in London early; if you return 16 November at 20:30, you have the morning and afternoon to explore.
Best time to travel
October–November and February–March see less mass tourism and kinder fares. Skip Christmas, Easter, and July–August. If you're flying for work, Wednesdays and Thursdays have less leisure crowding; for a break, any day works, but plan ahead.
What to do in London
Dozens of options: Big Ben and Parliament, Tower of London, free museums (British Museum, National Gallery, V&A). The Thames, Greenwich, Portobello Road on weekends. Use an Oyster Card on public transport to save. Eat at markets (Borough, Camden) rather than tourist restaurants. Stay in areas like Bethnal Green or Elephant & Castle for better-value accommodation.
FAQ
Are there direct flights Dublin to London?
Yes, Ryanair flies direct with no stops. The journey takes just under 2 hours.
Why is this flight so cheap?
It's a heavily competed route between Ireland and the UK. Ryanair operates at low cost and the short distance helps. Return fares from €42 are possible because there are no middlemen and demand is spread.
Which London airport does Ryanair use?
Ryanair lands at Stansted (35 km from central London). Fast trains and coaches connect to town. Other options (Gatwick, Luton, Southend) are further out or pricier; Stansted is efficient from Dublin.
Do I need travel insurance or extra baggage?
Ryanair includes a small backpack. A suitcase costs extra. Travel insurance is never a bad idea on international flights, but the core deal-€42, is hard to beat.
