Airlines sometimes miss that the key question for a lounge isn’t “are there enough seats for passengers?” but “is there enough space and enough empty seats so the lounge doesn’t feel full?”
If a lounge feels just as packed as the gate area, it isn’t a peaceful escape from the terminal. I’ve been to too many lounges that feel like refugee camps during peak times. You have to hunt for a place to sit. Staff can’t keep up with the turnover and trash piles up. Food and drink go unreplenished.
