I had what turned out to be a very minor problem, but Swiss Air acted very ptomptly. I called at 8:45 in the morning and the tech was at my door by 9:45 am. He assessed the situation and my issue with the heating system was cleared up in 10 minutes. I am relieved that the problem is taken care of and I am ready for the rest of the day with this taken care of Thank you Swiss Air!
