Thank you all for the helpful replies.
My questions arose from this situation: I originally booked fully refundable tickets on Lufthansa (Denver–Munich, Munich–Bologna, Bologna–Munich, Munich–Denver). I intentionally paid extra for refundable tickets so we would have flexibility if a family member in the U.S. had a medical emergency and we needed to change our plans. I’ve also booked hotels and Airbnbs that allow cancellation for the same reason.
I assumed (apparently incorrectly) that I could cancel or change individual legs if needed. We considered canceling the Bologna–Munich flight, taking the train instead, and extending our return by one day. After 38 minutes on hold with Lufthansa, I was told it would cost $794 to cancel the Bologna–Munich segment. The agent also said she couldn’t tell me the cost to change the Munich–Denver flight until after the flight was canceled. The only way to receive a refund, she said, would be to cancel the entire itinerary and rebook.
When I checked online, the same flights (Denver–Munich, Munich–Bologna, Munich–Denver) are now $2,575 more than what I originally paid.
That led me to wonder whether it might make more sense to book nonrefundable tickets (at about the same price as my original refundable fare) and rely on trip insurance instead. Specifically, would trip insurance cover us if a family member in the U.S. had an emergency and we needed to return home early? It sounds like trip insurance has a lot of caveats and may not be the best option.
At this point, we’ll probably keep the flights as originally booked. Lesson learned: “fully refundable" doesn’t necessarily mean individual segments can be changed without additional cost.
Several of you also mentioned travel medical insurance, which I do plan to purchase. Is Allianz a good option, or are there other companies you would recommend?
Thank you again for your replies. They are sincerely appreciated.
