AirAsia Bhd allocates about 20 per cent of its revenue every year as part of continuous efforts to improve operational efficiency as well as travel experience for customers.

Its Chief Executive Officer Aireen Omar said there were many plans in the pipeline to promote seamless travelling experience for customers.

"Every year, we are continuously improving our services. We always innovate the way we do business, always ahead of the game as well as finding ways for passengers to have a pleasant travel experience with us," she told reporters after the launching of new self service features at Senai International Airport here, today.

For financial year 2014, AirAsia recorded a revenue of RM5.4 billion.

AirAsia today unveiled its self bag-drop and home tag services, which are currently being tested at the Senai International Airport, making Johor Baharu the first AirAsia station to offer a complete self-service experience to its guests.

Self bag-drop enables guests to check-in their baggage by themselves without having to queue at a check-desk while home tag allows guests to print their bag tags at home together with their boarding pass.

Aireen said Johor Baharu was chosen as the first hub to deploy these new services due to a high percentage of take up rate in terms of self-service features.

"We recorded a high percentage of up to 70 per cent of guests using self check-in and self bag tag here, making it deal to test a brand new feature," she added.

She said these new features would be then made available at Don Mueang Airport, Phuket, Langkawi International Airport and a few airports in Indonesia in the coming months.

Among other innovative implementations by the low-cost carrier are the introduction of Wi-Fi on board, self bag-tag and many more.
