I just got an email from Citibank regarding some changes in their T&C.
One of the biggest one for me is that the Citibank International Transaction fee will now be charged for Citibank Plus (as they are removing the exclusion)

UPDATE: I have just called the Citibank call center and they they have confirmed that the fee will NOT be applicable to Citibank Plus accounts (as per the FAQ)

Will there be additional charges as a result of this change?
No. The fees and charges for your account remain the same.
Sorry my late reply. They took a while but after some more emails they gave me a more personalised answer.
In February I did more international transactions online and in store (in UK actually) with no fees. Citibank informed me the previous fee was charged by the vendor. It seems strange as it only happened once but so far so good. Have a safe trip to the UK.
