We are making some improvements to our seat assignment process. In order to minimise the impact of these changes on our passengers, we need to restrict the number of seats allocated within the system, throughout the period of development. From 9th January 2012 we will only be able to offer advanced seat selection for flights departing before 01 November 2012. This policy applies in every cabin. We will add any updates on progress to our website and when the system changes have been completed, we will once again open up seat assignment to 336 days before each flight.
Please donít forget that all seats, on every flight will be available to select when check-in opens (this is at -24 hours for mobile and on-line check in). In exceptional circumstances some seat allocations may be moved due to operational requirements.
