Expedia, one of the two online travel agencies in feud with American Airlines, has removed fare details of American Airlines flights from its site, escalating the dispute between the airline and the travel site.

The sale of American Airlines flights on our website has been suspended. We remain open to doing business with American Airlines on terms that are satisfactory to Expedia and do not compromise our ability to provide consumers with the products and services they need, Expedia announced in a statement.

Meanwhile, American Airlines claimed in December that it has seen a year-over-year increase in its overall ticket sales after it pulled its schedules and airfares details for American Airlines and American Eagle flights from Orbitz.com. Following the closure of American tickets sale on Expedia.com, the airline also claimed that fliers who will buy tickets directly from the airline, will be offered combined package deals of hotel and flight.

However, according to industry experts, American Airlines sale can drop after Expedia's action.

Further to boost the business, American Airlines that has more than 3,400 daily flights on average, has shifted to other online travel agencies, notably Priceline.com, Kayak.com, and its own website, AA.com.
