LOL. Can't say I'm surprised. United either doesn't know what it is doing (I am giving them the benefit of the doubt and going with this option) or they purposely are making changes to eliminate high margin business and outright lying about why they are making these changes. I will give two examples which certainly don't prove what they are doing but do provide a trend:

1) They seriously devalued the PassPlus Secure program to the point where I haven't come across anyone who has renewed their contract since they made the changes. I'm sure that some have but its a low percentage. If they wanted to kill the program because they thought it was unprofitable they should have just killed the program. Instead they just slashed the program in many petty ways that are just irrational. Keep in mind that the customers who paid for this program are those who value full fare tickets and buy them.

2) By removing the ability to see JN and PN availability through this "expert mode" change United has in effect killed the YBM instant upgrade program. I don't have a problem with them killing that program. But please just kill that program. Don't be either stupid (which I think they are being) and not see what the effect of your actions are or be deceitful and throw out some nonsense about why you are making the change. Either way it doesn't paint United in a pretty light. If someone else has a third alternative whereby the airline is not chasing away people wanting to by F,A,J,C,D,P,Z,Y,B,M in order to prevent "confusion" by people buying the lowest possible fare buckets I'd love to hear it. Sounds like some serious paranoia by United if I'm wrong and they aren't just in over their heads and don't know what they are doing.
