I took China Airline about 5 years ago. From New Delhi to San Francisco Airport. Someone I know had recommended it because the "benefit" was - you fly from Delhi, get a stop over for one night (hotel and food provided) midway, and reach fresh to San Francisco.
I had 3 seats going. On return, the airline would not confirm my return, and I was forced to buy 3 one way fares back. I ended up spending twice the money.
I would not even fly China Airline, even if it was a free fare.
Also, FYI, while the hotel was okay, the food was very bad, and I am a person who can eat almost any cuisine in the world. The food was just plain - BAD.
