Agreed......! We need to stop trying to find excuses and start recognizing that there is a problem...., if you look at the best performing airlines around the world..., you just cannot pin "subsidies or young cabin attendants" as a common denominator..., many of the best airlines in the world operate in a very competitive market with work rules as demanding if not more than those in the US..., many of them have a very senior staff as well.
They just do a better job, plain and simple!
