According to a rep who did at least 45 minutes of research (and called me back), SprintPCS does not offer ANY bonus miles on ANY airline in connection with the monthly invoice amounts. Northwest & Alaska used to be 5 or 7 miles per dollar on each invoice.
Now all bonus miles are only in connection with promotions, not invoices.
In other words, they gave me 2,500 UAL bonus miles when I switched from the expired WorldPerks plan to MileagePlus. There will be another 2,500 bonus for me in a few months. But other than that, I am not going to see any more miles from SprintPCS.
Is anyone anywhere getting bonus miles for their SprintPCS invoice amounts? I'm dying to prove that rep wrong.
