Price for upgrade from M to Z on CPH-PVG
Hi.
Are there anybody who paid for upgrade from M to Z on CPH-PVG. Currently, optiontown says 336 euro ex. sign-up fee on my travel date.
I have before tried upgrades on CPH-PEK and CPH-NRT, the prices are usually 285 euro ex. sign-up fee.
336 euro is the standard price for CPH-PVG, or it is because of the dates I flies on?
Thanks for your help!
