Hello, my name is Elena Gilbert, and I’m here to help you forget about your concerns. I’ve been a travel agent for several of the major airlines for the past seven years. You may also contact me and ask for assistance anytime you need it. I’m available to my clients 24 hours a day, seven days a week, and I go out of my way to make sure they’re satisfied with the outcomes. I’ll walk you through the flight cancellation procedure and explain how each airline handles cancellations if you give me a call.
