There are many options—one of the most popular ones is the BabyZen YoYo. It can fold small enough to fit in overhead compartment and also can fold one handed. Parent facing to 6 months then forward facing after that.
If you would prefer parent facing another option would be the bugaboo ant—can parent face past six months. It also folds down to cabin size and can be pulled as a trolley. However the fold looks much more complicated. The handle rotation is rather annoying as it doesn’t always click into place—and that was in the shop (have seen reviews saying this too!). It also felt like a dolls pram compared to the other Bugaboos and I’m only 5” 
Bugaboo bee is also another good option, it is bigger than the ant and can both parent face and forward face and also has the option for a carrycot. The seat is larger than the ant so if DC is likely to be tall it’ll certainly work out better than the ant! It also feels less flimsy than the ant.
ICandy raspberry is very similar to the bugaboo bee (looks wise). But I have seen some reviews that say it’s better and lighter, others that say it’s worse and heavier so it seems to be a marmite pushchair.
City mini is a good one too, and can take a carrycot. They also do a lighter version that folds smaller, the city tour. Both can fold one handed in one step.
The Uppababy Cruz is also a lightweight pushchair, but the most expensive out of all of these. It is suitable from birth if you buy the carrycot separately. They’ve recently brought out the new one and on the photos it looks larger than it used to be.
The iCandy lime is also a light pushchair which can be folded one handed, and is slightly similar to the Uppababy Cruz. It can face both ways, includes carrycot and I believe it is slightly cheaper. The lime actually has a built in buggy board so would be good esp if you decide to have another child in a few years.
Others to consider would be the Joie pact, Uppababy minu, cybex Eezy twist and mountain buggy Nanu
All of these are compatible with car seats when using adaptors.
