Which domestic airline has the best service and which is the worst?

Spring Airlines is one of the garbage companies, and the service attitude of the staff is extremely bad! Spent a lot of money and got angry. 201April 2, 91day hitchhiking is disgusting! A 20-inch standard suitcase is not allowed on the plane. If you want to bring it, you must send it to 150 yuan for consignment. I will never fly by Spring Airlines again in my life. The flight is 2019 April 2 1 afternoon 13: 15 Yinchuan-Yancheng. A special window for checking luggage was set up in the Spring and Autumn Period, and the service attitude of the service staff was very poor. Actually, it's a threat+money collection, MLGB. I wish Spring Airlines an early closure, so as not to take up route resources and affect our trip. Because you occupy the route, regular airlines can't get this route, which of course affects me!
