Yep! Its pretty awesome, you take it to the end of the walkway and leave it just as you enter the plane.
Just a suggestion: take any removable parts off of your stroller before you check it. They are pretty rough with them and they get tossed around a lot when under the plane as they are usually just thrown in at the last minute.
I would also suggest getting a stroller bag to protect your stroller if it is anything more than a cheap umbrella.
