It is doable but will be stressful. Make sure to really study the airport map and to know exactly where you are going. It is pretty well marked but know what gate you are going to and where the gate is. Do,the obvious such as being as close to the front of the plane as possible and not gate checking anything. It is really about a five to seven minute walk at a fast clip from where the shuttle comes in to most of the international gates but that is moving fast and making no wrong turns like I said it is well marked but watch the signs and make sure you know your gate.
