In addition to all the well-thought-out things you’ve said, it isn’t always possible to cancel a flight and get your money back. About five years or so ago, I cancelled a flight because the concert I was planning to see was cancelled. The airline would not refund my money, but would only give me a ticket for the same flight in the future. I never had cause to take the same flight. Total loss of air fare.
Even if you change your flight, there’s a pretty hefty charge.
My post isn’t about being stranded on the plane (was once, learned to plan for that) but a very silly questions that I’m sure the aviation experts can answer. Ready?
How do I fly with my grandson’s goldfish about 3500 miles, 4 airports? Without buying the fish a seat, and without freeze-drying the fish, of course!
