They are in competition with Swiss and Easyjet, and I think for the Bernese they are offering an excellent service.
Please spread the word, if we don't use it we'll loose it, like all the others that have gone before. At least this one has a decent price.
The Bern airport bus departs from the Post Bus station, upstairs above the railway station, near the car parks.
