Changing ticket with lower fare & change fee
I am thinking of changing my Christmas ticket from DOH-NCL-DOH to AUH-NCL-DOH.
There is a change fee of about GBP 70 but the difference in fare is about GBP 80. The cancellation fee is GBP 70 too.
There is plenty of I class availability.
If I just change the booking will I pay the change fee and get the difference in fare back? Or should I just cancel and rebook?
