When booking through a travel agent, it is important whether the agent knows about the subject and is able to give the customer the information he/she needs. Prices in travel agencies are higher than online so the customer expects the service which he/ she is additionally paying for. Even if the internet is a low-contact channel people may expect some form of consultation maybe via email or through a specialized online chat. The same applies to the call center, even though people might already know what they want, the operator needs to be prepared to answer any specific question about the flight or the before and after flight.
