I asked for wheelchair assistance. When I got to Copenhagen, there was none. Luckily I found a robot type wheelchair that got me to my next gate. In Dusseldorf, there was no help at all. On the return trip, SAS bumped me and sent me to another airline without provision to get to my final destination. I had to make other arrangement to get home which was VERY expensive. I do not understand them, they treat Americans like trash.
