Double pushchair for travel

[pumpkinposey]

Now travel is hopefully opening up again we have lots of holidays to squeeze in once our newborn is here. All being well we will have a 19 month age gap so looking for recommendations for a travel stroller that will be lightweight, easy to throw on a plane and suitable for a baby and toddler. So far I've looked at:

Mountain Buggy Nano duo
Baby Jogger City Tour double

Thanks!

Did you go for either of these two? I have been looking at the same ones but not sure whet to go for.
