On several flights we have taken in the last few weeks, we have noticed at least half a dozen passengers passing through TSA with their walking sticks . In fact, two passengers, seated close to us both had minor issues placing their sticks in the overhead bins . yes, the wheelchair services seem efficient and I have noticed they pass through TSA and immigration at a faster pace…. However,once you leave your destination airport, you are stickless… my advice take your stick and use the wheelchair service. arrive early as they seem to be in much higher demand .
