Description

You can change a flight up to an hour before the scheduled departure with an $80-US charge if you booked directly with Emirates online, or $100-US if booked with a travel agency. If you wish to cancel or modify or change the flight your booking via the Emirates manage booking options, you must do it within the first 24 hours of the initial booking to avoid paying an Emirates Ticket Change Fee or alteration fees. Emirates allows passengers to modify or cancel their flight bookings via its Manage Booking tool.
