Air Canada (AC) and its Aeroplan loyalty program are locked in an active federal lawsuit against Seats.aero, the popular award flight search platform, after the airline filed suit in the United States District Court for the District of Delaware on October 19, 2023, alleging that the tool’s automated scraping of Aeroplan award availability data constitutes computer fraud, trademark infringement, and false advertising, View From the Wing Flagged.
The case, filed against Localhost LLC — the corporate entity behind Seats.aero — originally named Ian Carroll, the site’s founder, as the primary defendant. The airline’s core position is that large-scale automated harvesting of its award inventory data violates both Aeroplan’s terms of service and the Computer Fraud and Abuse Act (CFAA), burdens its server infrastructure, and misappropriates its trademarks. Seats.aero denies those claims and has since escalated the dispute, filing counterclaims alleging antitrust violations, tortious interference, and unfair competition.
As of May 2026, nearly three years into litigation, settlement talks that reached an impasse on February 17, 2026, have not resumed, the site has brought in new legal counsel, and Air Canada is now fighting to prevent the newly filed counterclaims from proceeding at all — arguing they arrive too late in the litigation timeline. Seats.aero is now being run by Chris Lopinto, who founded ExpertFlyer, a veteran of travel search technology whose earlier platform removed Air Canada and Star Alliance award data in response to a separate legal pressure campaign in October 2023.
Why Air Canada Is Suing Seats.aero — And What It Alleges
Air Canada’s lawsuit rests on three distinct legal theories, each addressing a different dimension of Seats.aero’s data collection and display practices. The airline alleges both screen scraping and API scraping — two technically distinct methods of extracting award availability data from its systems — with the harvested data used to populate Seats.aero’s website, including its paid commercial subscription tier.
Air Canada’s specific allegations against Seats.aero include:
- CFAA violations: Automated bots continuously searched for and harvested award data from Air Canada’s website and systems in direct violation of Aeroplan’s Terms of Use, which explicitly prohibit automated scripts, robots, crawlers, screen scrapers, data mining, derivative works, and circumvention of blocking measures.
- Server burden and outages: The scraping activity allegedly placed a disproportionate load on Air Canada’s infrastructure, causing website outages and straining Air Canada’s downstream relationships with Star Alliance and partner airline systems.
- Trademark infringement and false advertising: Seats.aero displayed the Aeroplan logo and Air Canada branding alongside search results without authorization. Air Canada is seeking statutory damages of up to $2 million for each type of service sold, offered, or distributed by Seats.aero under the Air Canada and Aeroplan trademarks, in addition to actual damages exceeding $75,000, disgorgement of profits, and attorney’s fees.
According to Air Canada’s court filings, Seats.aero sometimes displayed up to 265,552 Aeroplan-available routes, implying that many API shopping requests were being made over any two-day period. The complaint described Carroll’s operations as “frequent and rapacious, causing multiple levels of harm” and characterized his methods as purposely circumventing the company’s security mechanisms.
Seats.aero’s Defense and its Legal Traction
Seats.aero contests each of Air Canada’s allegations on both factual and legal grounds, and the site has received at least one early procedural validation: a U.S. federal judge denied Air Canada’s motion for a preliminary injunction in March 2024, ruling that the airline had failed to demonstrate a clear breach of Aeroplan’s terms or imminent irreparable harm. That decision allowed the site to continue operating through the duration of litigation — a significant early win for the defense.
The site’s key counter-arguments are as follows:
- Data is publicly accessible: The award availability information Seats.aero retrieves is not locked behind authentication walls in the legally relevant sense — it is data that any member of the public with an internet connection could access manually.
- The API is not the “website”: Air Canada’s Terms of Use govern its website, and Seats.aero argues that the Amadeus reservation system, which operates the API in question, is a distinct and separate technical system not clearly covered by those terms.
- Amadeus complicates ownership: The involvement of Amadeus as the reservation system operator raises questions about who actually owns the degraded server resources at issue in Air Canada’s infrastructure claims.
- Rate-limiting protects the airline: Seats.aero imposes rate limits on its requests and contends it did not cause the outages Air Canada attributes to it. The volume cited by Air Canada — roughly 265,552 route checks over two days — amounts to approximately one API call per second, a load that should not burden a modern commercial-scale system.
- Users reduce direct load: When Aeroplan members check availability via Seats.aero, they do not separately query Aeroplan.com, which may actually reduce total demand on Air Canada’s systems.
- No consumer confusion: Displaying an Aeroplan logo next to Air Canada search results within an independent search platform does not constitute trademark infringement because no reasonable consumer would mistake Seats.aero for Air Canada or Aeroplan itself.
In a statement issued at the time the suit was filed, Ian Carroll said he was “disappointed” with Air Canada’s decision and noted that he had worked with Air Canada in the past to resolve serious cybersecurity issues in their own systems and was compensated through Air Canada’s bug bounty program. Air Canada did not confirm this claim. Carroll also stated that he had repeatedly offered to modify how scraping worked and that Air Canada had ignored those offers before filing suit without attempting mediation.
Air Canada Has a Stronger Ground on the “Trademark Claim”
While the CFAA claim faces significant legal headwinds, Air Canada’s trademark argument is more legally viable — and precedent exists in aviation for its success. American Airlines’ trademark suit against Skiplagged, which the airline pursued over the hidden-city ticketing search tool’s use of its branding in results pages, demonstrated that displaying a carrier’s marks without authorization in a commercial context can constitute actionable infringement, regardless of whether consumer confusion exists in the common-sense understanding of that phrase.
Seats.aero displayed the Air Canada and Aeroplan logos when presenting search results, and while the site included a disclaimer stating it was not affiliated with any airline, Air Canada characterizes the display as infringement, dilution, and false advertising. The strength of this claim — and its potential exposure of up to $2 million per service type — likely constitutes the most immediate financial risk facing Seats.aero in the litigation.
Seats.aero’s Counterclaims Include Antitrust, Tortious Interference, And Unfair Competition
In a move that substantially broadens the litigation’s scope, Seats.aero has filed counterclaims against Air Canada and Aeroplan alleging antitrust violations, tortious interference with business relationships, and unfair competition. The theory underlying these claims is that Air Canada is not genuinely seeking to protect its infrastructure or intellectual property, but rather using the legal system to eliminate a third-party tool that makes its loyalty program’s award availability transparent — and, by extension, harder to manage for maximum breakage.
Air Canada is now attempting to have these counterclaims excluded from the case on procedural grounds, arguing that the original pleading amendment deadline has passed, that discovery was largely complete by last summer, and that allowing new claims would require extending depositions and discovery in a way that would substantially delay proceedings. From Air Canada’s perspective, the counterclaims arrive too late and would expand litigation indefinitely.
