Canadair Regional Jet CRJ-900 (N242LR)

The ghost plane. I flew on this one MFR-PHX on 21JAN2022. It was a cold foggy morning before sunrise, parked out at the end of the longest walkway. We couldn't see it in the fog until we were right up to it, as it blended in.
It appears this was previously stripped of all American Eagle livery pending retirement, as Flight Aware shows it flew PHX-TUS on 27JAN2022 and has not flown under this registration since.
