e-ticketing in Dubai/UAE

Re: e-ticketing in Dubai/UAE

seriously? cuz i was looking at expedia and travelocity and one of them was cheaper =O so which one of these websites is cheaper then? and would it be better for me to buy the ticket directly from the airline? (though air france told me a higher different price when compared to the travel agency, while etihad told me a different one =/ )

this stuff's confusing =(
