With direct flights to Dublin hitting $1,400 one-way while connecting flights through Dublin to other European cities cost just $400-600, travelers are increasingly tempted by skiplagging—booking the cheaper connecting flight and simply not boarding the final leg.
A thread on r/TravelHacks asking about skiplagging specifically on Aer Lingus reveals the economics are compelling, but the risks are real and often misunderstood.
The Price Discrepancy
The numbers are stark enough to make any budget traveler furious. A direct summer flight from the US to Dublin on Aer Lingus: $1,400 economy one-way. The same first leg to Dublin, but continuing to Paris, Barcelona, or other European cities: $400-600 total.
That's not a minor difference—it's a $800-1,000 savings for literally the exact same seat on the exact same flight for the first leg. The pricing makes zero logical sense from a consumer perspective, which is precisely why skiplagging exists.
How Airlines Price Routes
The counterintuitive pricing stems from airline hub economics and competition. Dublin is Aer Lingus's home hub with limited competition on direct US routes, allowing premium pricing. But routes to continental Europe face fierce competition from other carriers, forcing Aer Lingus to price aggressively—even when those flights include the expensive Dublin leg.
As one commenter explained: "They're not pricing based on cost per mile. They're pricing based on what the market will bear for that specific route."
The Risks: What Actually Happens
Multiple experienced travelers weighed in on the practical risks of skiplagging on Aer Lingus specifically:
No checked bags. This is non-negotiable. Checked luggage gets routed to your ticketed final destination. Several commenters emphasized: "Carry-on only, and make sure it fits size restrictions. If they gate-check your bag, you're screwed."
One-way tickets only. If you skiplag the outbound flight, the airline will automatically cancel your return. "Book two separate one-way tickets," multiple commenters advised. The original poster noted they wouldn't have a return flight with Aer Lingus, which removes this particular risk.
Frequent flyer consequences. Airlines can and do ban passengers from loyalty programs or even future bookings if they detect skiplagging patterns. "Don't use your frequent flyer number," one traveler warned. "And don't make it a habit with the same airline."
Airline policy enforcement. Aer Lingus's terms of carriage technically prohibit skiplagging, but enforcement is inconsistent. "They're not checking at the gate if you're supposed to continue," one commenter noted. "You just don't show up for the second flight."
When It Goes Wrong
Several commenters shared cautionary tales:
"Gate agents sometimes ask at busy hubs like Dublin if passengers are connecting. Just say you're staying in Dublin if asked directly. Lying is risky, but so is volunteering information."
"If your first flight is delayed and they reroute you through a different hub, you're stuck taking the reroute or losing the ticket entirely."
"If there's a schedule change and they move you to a different routing, the skiplag opportunity might disappear and you've got no recourse."
The Ethics Question
The thread sparked debate about whether skiplagging is theft or simply consumer optimization of absurd pricing.
"Airlines created this situation with nonsensical pricing," one defender argued. "If they priced logically, skiplagging wouldn't exist."
Others countered: "You're agreeing to contract terms when you buy the ticket. Breaking that agreement is technically breach of contract, even if the pricing is stupid."
The practical consensus: airlines lose minimal actual money from occasional skiplagging (the seat was sold either way), but systematize it and they'll crack down hard.
Alternatives Worth Considering
Several commenters suggested legitimate alternatives:
Position flights. Fly budget to London or another European hub, then take a budget carrier to Dublin. Total cost often competitive with skiplag pricing, zero risk.
Norwegian or budget carriers. Check competing airlines thoroughly. Sometimes direct flights on budget carriers undercut legacy carrier connections.
Flexible dates. Direct flight prices fluctuate wildly. The $1,400 summer peak might be $600 in shoulder season.
The Bottom Line
Skiplagging on Aer Lingus can save $800-1,000 on summer Europe flights—but only if you: - Travel with carry-on only (no checked bags) - Book one-way tickets or separate returns - Don't use frequent flyer numbers - Accept the risk of itinerary changes destroying the plan - Can handle the ethical gray area - Don't make it a repeated pattern
For a one-time summer trip where saving $1,000 makes a material difference to your travel budget, many travelers judge the risk acceptable. For frequent travelers or anyone uncomfortable with the contract implications, the legitimate routing alternatives are worth exploring.
As one experienced skiplagge summarized: "I've done it three times on different airlines over ten years. Never had an issue. But I also never checked bags, never used loyalty numbers, and never did it twice with the same carrier. Your risk tolerance may vary."
