Step 1 - Search
To change your booking select the check box next to the flight you want to change, then click on the forward arrow button at the bottom of the page.
If you have a return booking you can select one or both flights to be changed.
In some circumstances one of your flights may appear greyed out, this could be because:
•The fare conditions do not allow changes to the flight.
•You have already travelled on the flight.
Select either 'Flexible with Dates' if applicable or 'Back' to go back to the Manage Your Booking page.
