sorry about the confusing title. There was a big mixup with my flight from London to Tampa on Travelocity. So they now agreed to change it for me any way I want and I have some business in Zurich I need to attend to. So my departure from London will be on Saturday September 8. So the only ticket Travelocity can find is lhr to gva on Saturday night and then gva to zrh on Sunday morning and then zrh to tpa in the afternoon. They can’t see the lhr - zrh - tpa ticket. Maybe it’s because it’s a 21.5 hr layover. Now my question is, does Swiss allow same day changes? I’m in business class on all three tickets. Can I simply ask tnem at the airport to change my ticket directly to Zurich from London? Or should I just plan on booking a hotel in Geneva? Thanks
