Reach out to LOT Airlines and inquire about their compensation policies and procedures. Airlines often have specific forms or online portals for filing compensation claims, so be sure to ask for guidance on how to access these resources. Additionally, check your travel insurance policy, if you have one, to see if flight cancellations are covered. Your insurance provider may have its own process for filing a claim in such cases. If you find it challenging to navigate these processes on your own, you can also consider using a specialized service like AirAdvisor. They are experts in helping passengers like you to claim compensation for flight disruptions. AirAdvisor can guide you through the entire process, making it easier and more efficient. Remember to keep all your flight-related documentation, such as your ticket, boarding pass, and any communication with the airline, as this will be essential when filing a claim.
