Almosr any reasonably standard-looking stroller can be used on flights, so you can take your Espiro Only for sure, just not s cabin luggage. With many airlines, as baby's luggage (some have this as a free thing, but you need to check with the airline of your choice), with other ones you will simply have to check it in. I wouldn't stress out about a travel stroller with a newborn if you're not planning travels right now.
However, if you do, and need a cabin-sized one, I would suggest the Ergobaby Metro+ which is comfortably padded, lies flat, and can even create this bassinet-like environment around your baby. A nice and sturdier option for a newborn out of travel strollers.
