About Aer Lingus
Aer Lingus is Ireland's flag carrier and part of IAG (alongside British Airways and Iberia), connecting Dublin and Cork to 100+ destinations across Europe and North America. The airline occupies a unique position as a value-focused full-service carrier, offering transatlantic routes with US pre-clearance at Dublin Airport — meaning passengers clear US customs before boarding, arriving at US airports as domestic arrivals. Avios points earned with Aer Lingus are interchangeable with BA Executive Club.

Booking tips for Aer Lingus
Compare fare classes carefully
Aer Lingus offers multiple fare tiers. The cheapest class may restrict changes and exclude checked baggage — compare the all-in price before purchasing.
Book long-haul 3–6 months out
Long-haul Economy sale fares sell fast. Set a price alert and move quickly when deals appear — the best fares are typically 3–6 months before departure.
Use miles for upgrades
Aer Lingus's frequent flyer programme offers excellent value for upgrades. Earn miles on Economy fares and redeem them for a premium cabin on long-haul routes.
Route via DUB
Connecting via Aer Lingus's hub at DUB can open up cheaper itineraries — especially when direct fares from your home airport are expensive or unavailable.
