Folks can anyone offer me some advice? I recently booked a Biz Class trip using miles for 2 passengers LHR to HK Via FRA so I could use my miles and travel LH who I think are a great airline. I now need to change my UK point of departure from LHR To Birmingham. However, BMI DC say that because the LHR and HK trips are "Married Segments" they cannot change the first leg of the journey without cancelling down the HK leg and essentially re-booking the lot!! Now we all know that as soon as the 2 biz seats I have from FRA to HK are cancelled down there is a good chance the system will swallow them through others being wait listed or something!! can anyone help??

Cheers
