Airline booking question
Hi all,
Can anyone explain why I can't book certain carriers to certain destinations even though they fly there? Specific example is a one way trip in business class on emirates from Athens greece to Washington is 2k, but I can't book a flight from iad to ath, only the trip back. When I go to emirates website, and put starting airport as iad, Athens is removed from the destinations. So essentially I can't book a RT on emirates from the U.S. even though they fly to the destination...why is that?
Thanks
