Explanation:

Asynchronous communication is best suited to an e-mail application because the recipients are not required to be online for the sender to send the message.

A travel agency service is an example of a document-oriented Web service that better uses asynchronous communication. The service consumes time to process the document before it can get to a decision, therefore better not makes the client wait using synchronous communication.
