Lightweight Traveling Stroller

I am flying internationally by myself with my daughter on the 27th and I need a stroller that I can bring with me since I have a long layover. I am looking for the one that reclines so she can take a nap and laying on her back while we're waiting at the airport.. and also lightweight that I can check it in at the gate. My daughter will be 5-months old that day and currently 20lbs.  Any recommendations please? Thank you.
