At first, airlines' reservation systems preferred their owners' flights to others. By 1987, United States government regulations required SABRE and other American systems to be neutral, with airlines instead selling access to them for profit. European airlines' systems were still skewed toward their owners, but ''[[Flight International]]'' reported that they would inevitably become neutral as well.<ref name="fi19871010">{{Cite magazine |date=October 10, 1987 |title=Sabre crusades for neutral CRS in Europe |url=http://www.flightglobal.com/pdfarchive/view/1987/1987%20-%201976.html |archive-url=https://web.archive.org/web/20180509080431/https://www.flightglobal.com/pdfarchive/view/1987/1987%20-%201976.html |archive-date=2018-05-09 |access-date=2011-11-03 |magazine=Flight International |publisher=Flight Global |pages=6-7}}</ref>

For many years, [[global distribution system]]s (GDSs) have had a dominant position in the travel industry. To bypass the GDSs, and avoid high GDS fees, airlines have started to sell flights directly through their websites.<ref>Strauss, Michael (2010), [https://www.amazon.com/dp/0557612462 Value Creation in Travel Distribution]</ref> Another way to bypass the GDSs is direct connection to travel agencies, such as that of [[American Airlines]].<ref>{{cite web |url=http://directconnect.aa.com/Default.aspx |title=American Airlines - Direct Connect |publisher=Directconnect.aa.com |access-date=2012-11-08 |archive-url=https://web.archive.org/web/20120831061423/http://directconnect.aa.com/Default.aspx |archive-date=2012-08-31 |url-status=dead }}</ref>
