As a end user who actually charters Aircraft I made a few enquiries earlier this year from two companies. One a large worldwide organisation and one from a small established broker. Nice visit from the sales person at the large organisation blackberry et al no reponse to our request - smaller guy lots of advice, prepared to understand what we wanted and what we actually needed, not always the same. Suffice to say since April the smaller broker has been operating the charter for us with great success.
