Not saying you're wrong..... but
Why would you generate pueudonyms? Just delete it. Delete the To: From: fields for all email.
Delete the passenger name/number from every listing. This isn't information that's going to be used to follow trends, debug software, or optimize an airline. Instead of 'anonymizing' by replacing or obscuring. Anonymize it by simply blanking it out.
There's no need for them to know that 'Person A' communicated with 'Person B' this many times. It's not that kind of data analysis.
BUT!!
Interesting that you brought up email. Anonymizing a data field is easy. However anonymizing a free-text field (especially a long one) is frankly impossible. There are so many name/grammar variations, you'll never find them.
Ironically, you'd need an AI to even attempt it (hah) and at that point you've defeated the purpose.
