Lennuabi (meaning "flight assistance" in Estonian) is an Estonia-based service, acquired by Skycop in 2024, that helps passengers secure compensation from airlines for delays, cancellations, and overbookings. They handle claims, including legal representation, under EU Regulation 261/2004. They offer a "no win, no fee" model (usually 39.7?e, up to 50% if legal action is needed)
