We are traveling to see family next week and arriving at GVA on July 15. Does anyone know how far ahead of time you can fill out the online Swiss entry form? I can't seem to find an answer.
I noticed the online entry form (and backup paper form) also make you state your seat number on the airplane. We aren't issued a seat number until check in. FAQ list on the website says to enter any seat number for the time being. Then to update it via your smartphone once you have your actual seat assignment. I'm imagining myself having wifi issues at my transit airport and being stressed out trying to update a silly seat assignment! Maybe just filling out the optional paper form is simpler?? Thoughts or actual experiences?
