In June 2025, we introduced a new service for baggage claims related to lost, delayed, or destroyed luggage. We are present in the EU, the UK, and other international markets, with a focus on protecting the rights of air passengers globally. We have successfully processed over 510,000+ claims for clients from 221 countries, learning a 4.7-star rating from 26,600+ reviews. Currently operating in 21 languages (with nine more forthcoming this year), AirAdvisor is an ambitious and fast-growing startup with a clear vision for international expansion. We plan to reach 1 million claims by the end of 2026.✈️
