from their site
"GDS distribution
easyJet is now also available for bookings through business travel agents using Amadeus and Galileo global distribution systems (GDS). Please contact your travel agency or GDS account manager for further details. "

It looks like Expedia is using the consumer portal to book ticket (presumably cheaper) and upsetting easyjet :)
