An existing agreement between the pair allows customers to book via the Ebookers call centre and use loyalty points for discounts on products.
It is hoped that a full ebookers.com-branded site for RBS customers will be launched within the next three months.
Ebookers managing director Alan Josephs told Travolution: “What the RBS deal gives us is the ability to build the perfect loyalty programme for their customers.”
Meanwhile, Nectar’s existing point redemption scheme for travel products, which runs on an ebookers.com white label, is expected to continue despite this week’s announcement of deal for point collection between Nectar and Expedia.
Josephs added that the roll out of new ebookers.com sites and the implementation of a common technology platform across Europe is on-track with Austria and Netherlands now live.
A further eight countries remain on the relaunch programme for Ebookers before the flagship sites in the US, cheaptickets.com and orbitz.com, are overhauled.
A new marketing campaign for the Ebookers site in the UK is also expected to begin in September, a year on from when the UK & Ireland site first relaunched.
