Sorry about late response.
Fee: We take a percentage of booking fee. I'd rather not say what it is online but it's a fraction of what brokers charge as standard.
Safety: All except one of our US operators have Wyvern, Argus or both. In Europe it isn't that simple since EASA regulations have meant that there is little point in operators paying for the accreditation so there are only a handful that have it. When an operator does not have affiliation we do our own checks. We are not open to all but rather every single operator we work with has been vetted and has endured an onsite visit from the team. I don't think there is any other broker out there who has actually visited every company they use. I might be wrong though...
The reason we do not provide the operator details online is that we would have created a too good tool for bedroom brokers (or even the large ones) to be able to give real-time pricing which has always been the holy grail of brokerage. The development of Stratajet has so far cost $10M over 5 years (the level of tech in the pricing engine is insane) and therefore I am reluctant to give it to middlemen for free!
Finally, 56 Sqn then 7th Armd Bde.
