It's been a couple years since I've had to request missing miles from a partner *A flight, but it looks like US has upgraded their capabilities and now allows you to request missing partner miles on their website (the last time I did it, I seem to remember you could only request miles from missing US flights online, and for partner flights, had to mail in your Boarding Pass and ticket receipt). Has anyone had experience submitting a request for missing partner miles online? Did it take "up to 24 days" like they say it might? What was the timeframe? Has a request ever been denied? Just curious to hear how this goes.
