How does it work? There is no need to register - simply make sure your Etihad Guest number is in every booking. Fly '3' segments by July 31 2011 to qualify for the Miles Bonus Scheme. A segment is a single flight – London to Abu Dhabi for example. If you fly from London to Sydney return it counts as 4 segments: London - Abu Dhabi, Abu Dhabi - Sydney, Sydney - Abu Dhabi, and Abu Dhabi - London. Once you’ve qualified for the Miles Bonus Scheme, subsequent segments will benefit from double miles.
