Despegue,
The employer in the case is your Ltd Co, Ryanair are the client who you provide services to. The contract does not mean a lot, if your contract is IR35 compliant but your working practices show that you are clearly inside IR35 there will be penalties for you, not Ryanair.
I am sorry to say that there are no legal or tax reasons for Ryanair to concern themselves with IR35, the risk lies solely with you.
If HMRC decide to investigate your Ltd Co the costs in supporting this investigation can be substantial. It may be worth joining the Professional Contractors Group as they will provide support given a tax investigation as part of your membership.
