If I were not 1k, if would affect me. I check three on most flights. As said above the negativity in the press outweighs the infrequent extra collection they'll achieve.
It's a bean counter in an office saying look at what happens if I type $200 into the upsell column, and ignoring everything else.
With more or less constant criticism in the press these days, I am getting to the point where I think United should keep their mouth's shut unless they have anything nice to say.
