Mileage crediting is still not working properly.
Took an eligible partner flight in April. UAMP number on boarding pass. Three weeks later no mileage credit. Submitted the boarding pass and ticket etc by postal mail for credit. Nothing a few weeks later. Tried to use the web interface for a week straight - only received "error" messages. E-mail all information to UAMP service desk. Was told to expect credit "three weeks after approval". Three plus weeks later: Nothing. Write again to UAMP service desk. Was told to expect credit "three to four weeks after approval".
It has been nearly three months now. The best the new UA can do is to push out the delivery of simple processes more and more. Sad.
