I have read that getting Glacier Express seat reservations is very difficult because you have to be ready before the first day of availability for the date you want and start at midnight Swiss time. So, I went to the https://glacierexpress.ch/en website just to practice and get the experience of going through the process. However, tonight when I try to reserve a seat for any date within the 93 days period for 1st and 2nd class, nothing was available. It kept indicating "No connection found". The same thing happened when using my desktop or iPad. I even tried that Excellent seat reservation for 11 months out, same thing "No connection found".
What am I doing wrong? It cannot be that there is no seat at all for the next seat months!
