As mentioned above, you're paying for a load of marketing and a whole layer of management which is just not there at a modular school. These people and their resources must cost hundreds of thousands of pounds. Of course, this ulimately gets passed on to the customer.
It's really simple. Modular and Integrated are two very different business models. They have evolved from the days of 'self improver' and the more traditional option which is now integrated.
Integrated schools need to justify charging 40% more and offereing less hours. Hence the marketing and claimed 'contacts' with airlines.
Most integrated schools have a mixed reputation even with a marketing department. Some modular schools have an excellent reputation and NO marketing department. Says it all to me.
But, you pays your money and takes your choice, whatever works best for you.
