As a 1K:
The no change fee is nice, but the lack of credit for reduction of fares could be costly.
Otherwise the same day standby is something I already have and and I hope they prioritize it by status, not time of request, fare class, ticket price paid or the position of the moon and stars.
As a 1K, United has offered me little for just passing the reduced 1K 2020 threshold besides some PP. If I’m going to change airline loyalty, now is probably the time to do it. I’ve got 16 months to earn status with another airline or Airline alliance before my 1K benefits expire.
United has traditionally tried to inspire low level status fliers to move up....many times at the expense of their premium customers.
