Does anyone know how much is the limit weight for baby stroller on plane?

According to the SQ website, "The stroller must meet SIA’s standard cabin bag dimensions (up to 7kg and sum of length, width and height should not exceed 115cm) and must be able to be stored in the cabin overhead compartment." You can find the policies of other airlines in this article too! http://mommypoints.boardingarea.com/2017/04/23/airline-stroller-policies-around-the-world/

I think is more on the size of it. if you want to carry on board & not just b4 board leave it outside for the crew to check in then you have to get those cabin size stroller. There are many of such stroller in the mkt. some crew may still stop you from carrying on board but I always tell the crew the stroller definitely fits the standard cabin size measurements.
