After a year-long trial of one-way SMS onboard Singapore Airlines flights, airline technology provider SITA is to launch a commercial two-way service.
The company is working with several airlines to introduce two-way SMS and email by the end of the year.
Passengers will be able to send and receive SMS or email using their in-seat telephone handset.
SMS messages can be up to 160 characters, and users will be able to pay for the service by credit card or by using SITA"s Aircom prepaid calling card.
