I have been looking at this for months and still confused. I have a folding electric wheelchair that is good for smooth surfaces and light. I have a Quantum Edge 3 for getting out and about. stable but heavier. So do I take both and use the folding one at airports but is not that good for tourism, and the Edge 3 for tours. Do I just take the folding one and risk it not being suitable for tours. Do I take the Edge 3 and let the airline look after my mobility on the plane and airports.
