No. Seats.aero has repeatedly reached out to Air Canada and offered to adjust how we retrieve availability information from Aeroplan. Air Canada has ignored these offers and filed suit without any attempt at mediation.

No. Seats.aero is aware of both other award search tools as well as malicious third-parties such as mileage brokers that also retrieve availability from Aeroplan. Air Canada does not seem to have taken any public legal action against them. In many cases, they do not implement the same rate-limiting and protections against airlines that Seats.aero does.

No. Seats.aero prohibits mileage brokers and similar entities in our Terms of Service. Seats.aero routinely monitors for prohibited activity and terminates accounts when violations are found.

Most mileage brokers build their own tools to retrieve availability from Aeroplan much more rapidly than Seats.aero does.

Seats.aero retrieves availability from other airlines, including other Star Alliance airlines, at the same rate as we do for Aeroplan. We have always been willing to adjust the frequency that we search for availability on Aeroplan or any other mileage program, but Air Canada has never responded to our inquiries.

Air Canada's initial complaint is available here. Seats.aero's answer is pending.
