I absolutely DISAGREE on the 'what they charge for versus other airlines'. If you add in all the extras, the price ia almost always going to still be way lower. The seat pitch is very uncomfortable. But again, you know about that ahead of time. The only 'one flight per week' and not cooperating with other airlines is a way bigger issue. You know what all the extras will cost before you book the ticket. You either then book it or not, based on how much cheaper it is than your other options. Them cancelling the flight at the last minute and telling you that you're on your own to get there is a big problem.
