" Diego has been extremely agile and professional in handling our matters. He first advised us on an acquisition in a portfolio of aircrafts and later negotiated a complex restructuring along with a gainful exit for us. His ability to completely own up the client's cause and then utilise his experience to extract maximum value for the client, makes him unique. We have stuck to Diego for over a decade irrespective of whichever firm he was part of. Our trust in him remains undiminished for future. "

" As Accountable Manager at Sundair (German A320 operator), it is with pleasure that I recommend the legal services of Mr. Diego Garrigues to any potential client. Since 2017 we have worked together on aircraft leases from various operators and from different types of leasing companies, as well as on aircraft and engine purchases.

Some deals went through, others we had to cancel. In any circumstance Diego was fully focused on our interests, while highly respecting the other party. His ability to translate and simplify legal language to an engineer is amazing and he deserves utmost respect for his expertise.

Besides his extraordinary knowledge of the legal profession, what I really admire is Diego’s ability to see things from my perspective and act like he is a part of the company. In this way, he is able to insist on what is important, but also compromise in order to help the client to achieve his goal "

" As a first-time buyer I was shocked to find the complexity and amount of people involved in the acquisition of an aircraft. Brokers, operators, insurers, engineers, corporate service providers, tax advisors, and of course lawyers. Diego went beyond what one would expect from a lawyer. He not only drafted and/or negotiated the endless documentation involved but he also project managed the whole transaction for me, liaising with everyone involved and making sure the transaction was always moving forward. He is always available and most efficient. Highly recommend Diego Garrigues as your aviation lawyer. "
