I purchased an M class fare domestic and I am a 1k.
There is no availability in PN.
And I cannot get alerts for this in expert flyer.
Am I to login to United and check the flight 4-6 times a day manually?
The wiki says something about an "upgrade button". What does this button look like? Is it where the "CPU requested" is located when viewing a booking on united.com?
Here are some pictures of the app.
The 'cpu requested' changes to 'premier instant upgrade fare' when PN is open. Then you get a second screen asking if you really want to do it. Then it changes to 'confirmed'.
