How much does it cost to bring a stroller on a plane?

Excuse me, I was wondering if you could clarify the policy on bringing a stroller on board an airplane. Specifically, I'm curious about the associated costs. Does the airline charge a fee for transporting a stroller, and if so, how much is the typical cost? Additionally, are there any size or weight restrictions that I should be aware of before traveling with my stroller? I'd appreciate any information you could provide to help me plan my trip accordingly.
