Honestly, it depend a lot on the airlines. I would say that some company are bending the rules. I used to fly on China Airlines, and I never had a bad experience, and it was identical with China Eastern, but since the near miss in Shanghai I am a bid cautious. However, I will be traveling again with them soon to go to Canada, as their business class fair are affordable. I hope this will help, and don't miss the review in late March. Cheers
