Cost of changing names on flights?

[vigglewiggle]

Does anyone know roughly what the current charge is for changing the name on flights with Jet2? Their website just says "you will be charged the current rate." So not tremendously helpful!

If you read on through the very small print it says the charge is £27.50 per person per one way flight

BA is £30.

Thank you - I see you also get charged a credit card fee .
