After arriving at Suvarnabhumi from Melbourne on Thai Airways my next leg to Seoul was with Asiana. Soon after arrival at the Thai lounge my phone started vibrating with TripIt notifications that my flight to Seoul was delayed. Initially by 40 minutes but a short time later that was extended to 2 hours and 5 minutes. The reason for the delay was heavy snow in Seoul and all flights on Asiana and Korean has been affected. As you can see in the below pic several flights delayed and others cancelled completely.
