Aer Lingus is Ireland's flag carrier, now part of IAG (the parent company of British Airways and Iberia). Aer Lingus operates from Dublin (DUB) and Shannon (SNN) to ten US cities: JFK, EWR, BOS, IAD, ORD, MCO, MIA, LAX, SFO, and SEA. The Dublin hub is uniquely positioned because of US preclearance — passengers from Dublin clear US Customs before boarding, arriving in the US as domestic passengers. This is a major time-saving advantage but doesn't affect change/cancellation rules.
Aer Lingus fare brands explained
Aer Lingus sells transatlantic flights in five brands: Saver (cheapest, no checked bag, $120 change fee), Plus (checked bag included, $120 change fee, refundable as voucher), Advantage (free changes, full refund), AerSpace (Premium Economy product, $75 change fee), and Business class ($50 change fee, mostly refundable). Saver is roughly equivalent to a "basic economy" and offers very little flexibility.
Preclearance and what to do if you miss your slot
Because Aer Lingus offers US preclearance at Dublin, the check-in deadline is 90 minutes before departure — earlier than the standard 60 minutes for most international flights. If you miss the preclearance window, you'll need to rebook on a later flight. An agent can often find same-day rebooking on Aer Lingus or partner carriers without paying a no-show fee, especially if you call before the original departure time.
24-hour rule and AerClub voucher mechanics
Aer Lingus honors the US DOT 24-hour rule for US-issued tickets booked at least 7 days before departure. Outside that window, Saver and Plus fares refund as AerClub e-vouchers minus a $180 cancellation fee. The voucher is valid 12 months and usable on any Aer Lingus or IAG partner flight (BA, Iberia). Advantage and refundable Business fares refund to the original card.
IAG group itineraries: BA + Aer Lingus combos
Aer Lingus is part of IAG, so codeshare flights with British Airways are common (especially BA's Heathrow-Dublin shuttle paired with Aer Lingus long-haul). If your ticket combines BA and Aer Lingus flights, the operating airline's rules apply to each segment for delays and disruptions, but the issuing airline's rules apply for changes and cancellations. Look at the ticket number prefix: 053 = Aer Lingus, 125 = British Airways.
