In my experience the enforcement of this varies, but I believe it should be enforced. While I try to never pass judgement about who is medically prebiarding (not all disabilities are visible), it does bother me when 5 adults board with the individual.
But the human side in me also realizes the need for exceptions. Ex: a dad is in a wheelchair and needs his wife to help him but the have two small kids. The kids can’t board alone!

Southwest follows nothing with there polices when it pertains to pre-boarding . I boarded A2 and there were 3 people who were on the the fligh and I am a third of the way back on the plane. All business travelers should boycott Southwest when possible until they have a realistic policy that they follow.
