Great value. I had heard terrible things about their food but they must have improved, as food was decent and I'd say above average for economy class. Cabin was well pressurised. Temperature was never too cold and I was comfortable wearing a short sleeved t-shirt. I paid substantially less than I would have paid with other companies and got a similar service. The only thing that annoyed me was that the use of mobile phones wasn't allowed at no point during the whole flight, even if airplane mode was activated. This is due to Chinese regulations and not specific to Air China.
