Can I bring a stroller and a car seat for my child?

Yes, taking into account the relevant cases:

For infants under 2 years of age who travel on a parent’s/guardian’s lap:

As part of the free baggage allowance, the passenger may bring a foldable stroller or a car seat.
If the passenger wishes to take both a stroller and a car seat, one of them must be checked in as part of the standard checked baggage allowance or as additional baggage (as a paid extra service).

For children aged 2 to 12 and infants under 2 who have their own seat:

As part of the free baggage allowance, the passenger may bring both a foldable stroller and a car seat.
Important: An infant under 2 years of age occupying a separate seat must travel in a car seat.

The car seat must be properly certified for use on board an aircraft and meet the required safety standards. This certification is usually confirmed by a label, for example: “certified for use in motor vehicles and aircraft.”
