According to the 2009 Airline IT Trends Survey, co-sponsored by SITA, IT and telecommunications operating spend as a percentage of airline revenue, is forecast to be 1.7%, the lowest level recorded since 2002, as airlines seek to reduce costs against a backdrop of $10.4bn in losses last year and an IATA forecast of $9bn in losses this year. A total of 72% of survey respondents intend to renegotiate IT supplier contracts and 70% will invest in solutions that lower overall enterprise costs. The study has found that 44% of respondents plan to offer 'change/cancel/rebook facilities' functionality to their web sites by the end of 2010, while 37% already do so.
