Easyjet already sells through resellers!
Bit strange, since Easyjet already sell via travel agents, our corporate agent can book me on Easyjet
from their site
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 :)
