Themis Advisory was founded by Joanna Kolatsis, a former partner in City law firm, following over 20 years providing legal services to the travel and aviation industries. Following her decision to leave private practice, she founded Themis Advisory which was born out of a desire to provide current, pragmatic legal and business solutions for the modern business world.

Joanna began her legal career as group head of legal for a vertically integrated tour operator in 1998. In 2008 she joined the boutique aviation practice, Gates and Partners, before joining Hill Dickinson as partner and head of aviation and travel in 2014 until July 2018.

Since qualification Joanna has specialised in the aviation and travel industries and her advice covers all aspects including airlines, tour operators, destination management companies, distribution and accommodation. Her expertise includes aviation and travel law, business travel, commercial and regulatory matters including the Package Travel Directive and ATOL compliance, aviation regulatory issues including passenger rights and general company commercial and contractual matters including booking terms and conditions, website compliance, charter agreements and complaints handling. Joanna has specific expertise in risk management, crisis management and criminalisation in air and travel incidents and she speaks frequently on this topic.
