Our travel insurance just covered illness. It must cover something because Mitzi said we'll probably get about $150 from it. At least that covers the cost of the insurance and the difference in the higher, "no-fee cancellation" fares. She said she's going to see what her American Express card may cover, since we paid for the flights with it. And then we'll appeal to Delta for some reimbursement.

The policy we bought specifically excluded weather, and I don't actually know if you can buy insurance for weather-related travel interruptions. Something to look into though.

C'est la vie, je pense.
