Travellers could refrain from booking trips online because of mistrust of the ability of travel companies to keep their financial and personal details secure. Due to these fears about security, more consumers are using the internet for researching than actually booking their travel online.

For Expedia, which conducts a vast majority of its business online, these perceived fears could considerably affect its revenues and margins. Any loss of data by any online firm, it need not be Expedia, could significantly undermine the public's trust in online transactions.
