I'm flying in to Zurich and plan to go from airport to Bernese Oberland, do at least one of the peaks there, maybe both, (expensive!!) then back to Zurich, and ultimately the airport. I don't have time to take any of the panoramic train routes, and I think the run from the airport to Wengen is only 3 or 4 hours if that makes a difference on which would be best. I'm looking for advice on availabilty of seats, amount of personal space, comfort, luggage room, or any other tidbit you have. I did do a search of this forum, and browsed Steve's and Fodor's guidebooks at the airport, as well as their respective websites, and did not find this question addressed. The money difference between 1st and 2nd if I buy the Flexipass is about US$150.
