You mean, something that even lower middle class people can afford?
Your comment rings sanctimonious to me.
While I agree that major airlines should do better in some areas, they are also just responding to consumer demand.
Should the people who cannot afford higher fares just exist in a lower caste where flying is not achievable? Those people for whom lower fares are the priority, you feel they just shouldn’t be able to attend a family member’s funeral or college graduation?
That is how things are in my extended family in the US. A spare couple hundred dollars for even a routine round-trip fair between major cities is still a very difficult stretch for them.
If grumpy people who can easily afford the flights are annoyed by the lack of frills and the cheapness, yet people who are less well off can possibly afford more flights, that seems like a positive overall for society to me.
