Itīs not alone the broker , also other competitorīs who came with larger fleets who have a discount MX contract etc....which lowers their costs....
When I operated 2 Aircraft for an Owner in a JAROPS organization I talked to all the neighboring operators and told them that we have the need to unite in order to stay around. Act as one company, don't get divided by brokers fishing for the lowest price, share pilots, have lower mx costs etcetc.
(Brokers are not all bad, some are good guys to work with and bring indeed clients you would otherwise not reach and if you treat them well they'll seldom bite you)
Most of the companies I talked to then are gone. Its like in the inner cities, not before long there will be only Vodafone shops and other big chains able to survive.
Hell, I could only get a few to share a jaropsbook to save money.
To many egos, to little teamplayers. Not enough imagination.
