Very limited knowledge, but Air India (a full-fat govt owned airline till recently) didn't really have any of this. Yeah it was losing money, but the customer facing aspects were mostly standard - if anything, more standardized than other private players.

One could make an argument that "Well look, it was costing the government taxpayer money!", and that's a valid point. But given how little the variation in prices are across airlines in India, it's similar to saying "The govt shouldn't do public transport if it loses money, even if society gains".
