I have just been on Easyjet's website as was toying with changing my April flight to an earlier date.
They now have a two price tier price charge if you want to do a name change or change to another flight instead of the standard charge of £35!
The high level tier is now a charge of £45 plus the difference in flight price if there are less then 60 days to your original departure date, and the lower tier is now £15 to change plus new flight price difference if you are planning on changing to a new departure date of more then 60 days!
Good for the 60 day or more tier but any more then less then the 60 day change is now an extra £10 per person
