I had booking with Air China, booked thru Justfly, Due to COVID-19, they told me to cancel my booking and I will get full Refund, but when it comes to Refund, they are make a lot of excuses, after 6-7 months of regular e-mail and Call every 2 Weeks, I just got $390 out of $1300, and they told me only this amount was approved by Airline.
