American Airlines and Kayak have settled their legal differences, and the travel search engine again is displaying the airline's schedules and fares.
The settlement ends a standoff between the two over cyber-searching competitive issues. American information dropped off the site in August.
"We're glad it all worked out," said American spokesman Stephen Schlachter.
"Kayak.com is delighted to once again display schedules and fares directly from American Airlines on both Kayak.com and SideStep.com," the search-engine company said in a statement. "Kayak.com remains committed to providing comprehensive and objective results to our millions of users."
The agreement comes about a week after the airline filed a lawsuit against Yahoo for trademark infringement. As with an earlier settlement of a lawsuit between American and Google, details of the airline's agreement with Kayak are being kept confidential.
Flight price quotes listed on Kayak.com no longer include links to Orbitz or CheapTickets directly below the individual search results as Kayak does for other airlines. The only link listed is to AA.com, American's site.
American had sued Kayak in August, charging the search company with breaking an agreement by pulling AA information from third-party websites so that users could click through and book on sites other than AA.com.
Kayak then pulled the airline's listings, claiming that American told Kayak it could display the airline's fares only if the search company suppressed the search results of competing Web sites.
Web traffic analysis company Compete said Kayak.com and SideStep.com were responsible for sending 1.3% of all visits to AA.com in June. Because the visits converted to bookings at such a high rate, Compete found, about 5% of all conversions on AA.com were directed through by Kayak or SideStep.
About 9.3% of the visits to AA.com via Kayak or SideStep converted to bookings in June, compared with the airline's website average per-visit conversion rate of 2.7%.
In its suit against Yahoo, American complained that Yahoo was selling advertising space based on search requests for AAdvantage, the name of the American frequent flyer program, or other American service marks. These sponsored links direct users to AA competitors. American asked for unspecified damages, legal costs and money for a "corrective" advertising campaign.
Yahoo said it had confidence in its trademark policies, and it is prepared to defend them in court.
