Air China Upgrades

If you wish to not invest more money for the upgrade, then there are two ways in which you will get the same. One is by using the mileage that you have to travel for the next ticket. And the other is by waiting for a complimentary upgrade that you often get 3-10 days before the departure of the flight. Use the code that the airlines provide and get your flight tickets upgraded for free. Air china upgrades can be done in these ways.
