I read it earlier. Good PR and marketing. Reality - a few of the scenarios they give would be benign to the airline as passenger likely won't benefit as much because of the huge reduction in travel
e.g. new parents - likely shouldn't be traveling as much within first two years. E.g. A Diamond (traveling Domestic) might reduce his/her journeys if the first child.
new career - unless job/role requires travel probably won't accumulate as much vacation (unless work from home) quickly to make it worthwhile
new career
#2 - if switching roles/career must verify the new corporation T&E policy uses Delta for its corporate account otherwise, might have to explain why choosing Delta whereas corporate contract is *A or 1W
Illness/Health - similar to previous - most medical things which keeps someone from travel are the same injuries/recoveries which requires that person to remain close to hospital
