  • Regularly handling claims arising out of EU and UK Regulations, and frequently advising aviation clients on the implementation and implications for their business of new and/or amended regulations.

Chargebacks and refund claims during Covid-19

Passenger liability

  • Advising regularly on the ever-expanding scope of liability regimes and regulations, and assisting with passenger claims handling.  As well as advising on the Montreal Convention, UK and EU regulations relating to denied boarding and passengers with reduced mobility (PRMs), conditions of carriage, and UK and European consumer protection legislation, we also handle global claims like the worldwide deep vein thrombosis litigation.

Greenwashing claims
