Is it suitable to take on a plane?
If you mean as a carry-on/cabin luggage, then no, it is too large for that. However, almost all airlines allow the so-called baby’s luggage - a (usually free) stroller that they will take from you when boarding and return to you when getting off. Be sure to check your options with your airline. For an ultracompact buggy, though, you’ll need to get something simpler and smaller.
