They are very guilty of shrinkflation in general. For example, first class used to get you access to the airport lounges. Now you need a very expensive subscription of some sort to get access.
But then again, these short flights are often CHEAP. Even in “first”, where the perk is…a wider chair, sitting near the front and better snacks i suppose.
Example: I can fly from NYC to Chicago for $80 in economy. In first it’s about $200 on delta. I certainly wouldn’t expect free access to a good lounge with decent food for free at that price. It would be hard for me to be disappointed as a flyer at those prices.
