The upgrade allows agents to book up to four staterooms at one time on the platform, instead of having to reserve them individually, across the company’s brands - Royal Caribbean International, Celebrity Cruises and Azamara.

Other changes include providing secure prices and inventory so that clients can book flights, hotels and transfers together as part of their package.

Another addition is designed to make it easier for families who book multiple staterooms by giving them just one invoice for all guests rather than by each stateroom so they get one overall package price.

AirWaves was launched in November 2017 after going through an extensive testing period with UK agents and is now being used by 6,500 agents in the UK and Ireland.

Amanda Darrington, sales director, Royal Caribbean UK & Ireland, said: “The success of this tool is evident in the level of adoption seen since its roll-out in November, with usage up 30% on its predecessor, Espresso.

“We are excited to roll out this new functionality and look forward to continuing to work with our agents. Our ambition is to make searching and booking our holidays quicker and easier than ever before.”
