To be fair, I doubt this was about how generous they were/wanted to be or didn't; I'd guess it was more a result of not putting together what might happen when COVID went on, and not paying specific attention to all the details. Don't forget, in April 2020, when the pandemic was just settling in, we had convinced ourselves that we'd be through it in 6 or 8 weeks, then travel would go back to what it was. Then a few months, etc. Then came the steep drop in travel...the lots of people trying to get refunds, the managing the new lower demand, the storing planes, furloughing staff, government funding, etc.....a lot of things kept happening, and this situation just likely wasn't at the top of the list.

I'd heed the other advice and try to ask for special dispensation...seems appropriate.
