I'm flying in July and need to find something to get DD's MA to the gate. Dh isn't flying with me, so I'm trying to make it simple. I've looked into getting the GoGo Kidz Travelmate. It's pretty $$, but someone is willing to sell me theirs for $60. Is that worth it? Or should I just get a luggage cart and strap the MA on that? Also, how easy is the Travelmate to use and do you have to take it off the carseat during use on the plane? I just had a hysterectomy so I can't carry much weight, so DD is going to need to ride in the MA. Thanks!
