This should be straight forward change + fee, right? Or will I also have to pay the difference in pts?
Or will they return of points and then I have to re-issue? Asking because I have a neg balance
Because you have a negative balance, you will be unable to change to a peak date. (because you need to pay more Avios) Presumably you are unwilling to make whole your negative balance and add even more Avios.
Your best bet is to pay the fee, change to another off-peak date and hope that the agent doesn't give you a hard time about your negative balance.
