This has happened to me about half a dozen times over the last two years and I've always been awarded United flight credit, but this time not. The iOS boarding pass does not provide you a United ticket number to request retroactive mileage credit. I received an American receipt, but the ticket number referenced is my original American ticket number -001, not -016.
Any suggestions on next steps?
Just call with flight date/number and last name, they can find you, and will apply mileage appropriately. Fortunately when changing airlines you are always booked into Y class for the bonus.
