I couple of weeks ago I got an email from Swiss about Travel ID being ready. Although at the end of the email (why of all places was it put at the end of the email for existing Swiss account holders) it told me that I will be told when I can migrate to Travel ID, I foolishly decided that the email can't possibly mean I have to wait for a further email in the future to be told when to migrate, otherwise why would they send me this email. I migrated anyway.
I could log in but not do much else, for those who can't even log in, you are not missing much.
I managed to delete my Travel ID and will create another one. Let's see what happens now.
