Thank you all for the suggestions. I've made the changes via online and to my dismay


They wanted to charge me 800kr (swedish) 68 pounds or 110 us dollars per seat. On the original PNR I was charged for my seats. Flying J class. Soo I am on the phone patiently waiting to speak with a lovely CSA. The story continues...
Just finished with a call with BA after 30 min..All is well..they apologized for the mistake of charging me again..All is well in the bubble.
