I just got my chargeback on LX F ticket reapplied as apparently LX sent their t&c to amex to support this. (little f....ers). I called amex, asked to reopen the dispute and sent them the
eu261 interpretation by EC on 18 March 2020 in supporting documents.
So much for thinking about going for HON - The way they have treated me will have ramifications on my choices when this is over.
