In the latest twist to the case of the dead rabbit, [an anonymous "airport worker" has told a reporter that it was killed by leaving it in a freezer locker](https://www.thesun.co.uk/news/3441324/united-airlines-bunny-death-mystery-takes-a-further-twist-as-its-revealed-rabbit-was-accidentally-put-in-jet-freezer-for-16-hours/), contradicting the accounts of United executives who have claimed the rabbit was well treated. United also hastily incinerated the body without the owner's permission, preventing any kind of autopsy from occurring. This all happened apparently at Chicago O'Hare.

My question is why an airline would have a freezer at all, and why would they be putting luggage or pets into said freezers. I mean when I make connections I kind of assume they are not putting my bags in a freezer. Do airlines have freezers?
