DO NOT BUY A TICKET WITH THEM -----~~ SPECIALLY "BUSINESS" and "PREMIUM ECONOMY"~~
IT IS A RIP-OFF.
I bought a PREMIUM ECONOMY ticket (they charge me $1600 for a $900 ticket), and then it turns out to be ECONOMY. They just charged me more for it and they didn't have any explanation. They were just sorry talk to the customer care.
DO NOT TRUST THEM.
