I think we will use the Sky Club. We both have carry-ons, which discourages us from trying to visit Manhattan. I am just three weeks post surgery for a hip replacement so rushing around is not appealing to me.
At JFK I will use the wheelchair service, but they will never leave me with the wheelchair. I have to go directly to the departure gate, switch from the wheelchair to a chair near the gate and just wait there. If we are in the Sky Club I assume the staff there will have no difficulty getting a wheelchair for me to reach the gate. Would you agree with that assumption?
