Wow. It must be the time of year. My MBA13's SSD also died a few weeks ago. I just ordered an OWC replacement (and battery too). However, I'm only going to restore macOS long enough to move my TimeMachine backup (/home only) into something readable by Linux. Catalina was the last straw for me. At the moment I'm writing this having installed UbuntuStudio on the SDXC card. The drive is deathly slow compared to SSD but it's working.
EDITED to add: I'm doing some homework to identify my next laptop. It won't be an Apple. Ideally something with an aluminium chassis, 13" screen, 32GB RAM, and 512GB SSD. i7 or AMD equivalent. Suggestions welcome!
