Hi all. Need to take a very short trip from LHR to ICN in Feb - will be taking the Thursday flight from LHR out, then the Saturday flight back, with a total of about 18 hours in Korea.

I already have an economy ticket on hold with my TA but am tempted to take a biz reward ticket if one is available. Could those that have experienced this route in economy and business let me know if it's worth the 100,000 odd miles, specifically what are the seats like and do they have in-seat power? Equipment is the 777 apparently.
