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.
Lounges have gotten significantly worse since Covid though with overcrowding issues (with some exceptions like KIX), so I don’t think it’s a particularly great loss. My card lets me pay some token amount to gain access to lounges but I’d rather spend that money to get an actual meal cooked for me rather than a buffet and then sit in a quiet corner of the terminal than a crowded lounge.
This varies: a family member of mine flew cross-country a few weeks ago first class (on the company's dime) and was given automatic access to the lounges there.
International first class / business class travel is a different category than domestic. I was just referring to domestic. It usually costs an order of magnitude more so there are still some decent perks associated with it.
Transcontinental flights often qualify when shorter ones would not. If your flight has lay-flat seats (I usually fly Delta, so think Delta One), your ticket for one of those will usually cover the lounges. Whereas a standard domestic first-class ticket does not.
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.
