So I'm trying to understand what Delta did differently than AA and UA that caused such an uproar and a new possibly revised response from Delta vs the middle finger AA and UA customers received from those airlines when there was a similar, albeit less broadly passionate blowback with their similar program changes.

So unless I'm missing something, the only significant differences I can tell between UA and DL now are the much higher spend requirement for Diamond vs 1K - but watch for the UA number to swoop upward in the next couple months - and the restrictions on lounge access for credit card holders, which I'm sure UA is gauging reaction to see if they can copy something similar.

Given these changes are on par with Delta's long term strategy of focusing on product not program, and their stated objective to remove a good portion of the elite rolls so they can prepare nicer benefits for those who pay up, I'm genuinely curious 1. why the disproportionate uproar here vs what happened at UA/AA, and 2. what do you want Delta to roll back?
