Air China review by Art 2017-04-24

I booked premium economic class of Air China CA986 from San Francisco to Beijing on April 8th. When I checked in, the ground staff told me that Air China changed airplane, so there is no Premium Economic Class. She asks me if I want to change my seat to first row of Economic class or refund. I want my refund, so Air China ground staff put a stamp on my boarding pass and signed it, and then asked me to find Air China staff for refund at Beijing airport. I went to Air China Internal Ticket Counter at Beijing Airport for refund. However the staff said my ticket was issued at USA and they CAN NOT process the refund to me. The staff asks me to call Air China US office for refund. I called Air China US customer service asks for refund when I back to US. Per Air China staff requested, I email my April 8th boarding pass photo. On April 22nd, I got a phone call from Air China. The lady told me the ticket price of economic class on April 8th is EXPENSIVE than premium economic class. Therefore Air China has no refund to me. What on the earth that economic class price is EXPENSIVE than premium economic class!!!!!!!!! I am extremely disappoint about Air China!!!!!
