Send an email to KLM support detailing what I've gone through trying to re-instante or get a new frequent flyer account. Thought of sharing since this makes me laugh (while crying):
"I literally just want to have a Flying Blue account (old or new), but have been unable to do this. Here’s the course of events:
When I logged in with my email and go to the Flying blue pages, It asks me to sign up for Flying blue.
When I then signed up, it tells me that I can’t sign up because I already have a Flying blue account.
When I reached out via chat, support folks told me that by account is so old that it has been suspended.
When I ask them to un-suspend it, they say they can't, but suggest to create a new account with a new email.
When I create a new account with a new email, it fails because it says “the email is already in use”.
The email is definitely not in use (I just created it), but I assume that my name and birthday are matched, and therefore can’t create a new account.
So I’m unable to use my suspended Flying Blue account, neither am I able to create a new one.
When I tell support via chat they say I should send an email to someone who would be able to reinstate my Flying blue number.
They make me sign a PDF and send it over.
Nobody ever replies to that email.
I then email KLM’s privacy officer to delete my account and all info (thank you GDPR).
They say they can’t because I’ve got a flight with them.
I then ask the privacy office to reinstate my Flying Blue account.
No reply yet, but I’m guessing they’ll ask me to contact support."
