Definitely. I and all my co-workers are very enthusiastic about it! It works 90 percent of the time. I don't know about some of Rudi's cities--I do know Toronto (Air Canada/Canadian terminals only--not the old terminal (2?)), Miami, all of New York JFK, and LAX. I had trouble getting it because of computer malfunctions (look way back to my experiences) but finally was able to get it in LAX while I waited.
