Ironwalt Brookfield is, for all practical purposes, Ryanair. Except for you. This is the same trick they use with the cabin crew, which is to use intermediary organisations to employ and train people on different terms and conditions. Very good for them, especially in P.R. and legal terms. The fact that an application to Ryanair ends up with a Brookfield offer tells you all you need to know.
Rhood what you say is undoubtedly true. But it does not change the reality for those who are not being paid. If you are not being paid the typical Ryanair argument that it has "nothing to do with them" is absolute codswallop.
All the signs are that Brookfield is the means used to achieve the non-payment of Ryanair pilots. But nobody should be in any doubt that there is not much difference between the two organisations in practice.
