Yeah they’re not very common in the US unless the kitchen was renovated for a “home chef” type. The average oven you go and just “pick off the shelf” in the US doesn’t have convection. I don’t know anyone with a convection oven, I’ve only seen home cooks/chefs on YouTube with them.
Convection has been standard for ovens for over 10 years. My 13 year old KitchAid oven from a big box store has convection. It wasn’t even promoted until air friers became popular.
Also all microwaves with bake feature are convection ovens. Again it was normal, but now they put big “like air frier” stickers on them to let people know.
I’ll take your word for that, I don’t know anyone who has bought an oven in the last decade. 😅 Every home/apartment I’ve lived in has had basic appliances and every home I’ve visited even with older mid-range hasn’t. I’ve also never seen a microwave with “bake” function in person. But I might live in a different circle than you as well.
