hi we have just booked for a Thai Airways flight in business class from London Heathrow in January as they have a special deal , it is about same price as evergreen with Eva Air and as far as comfort is concerned you cannot beat Thai in business class , economy is a different kettle of fish as they still have not upgraded the jumbos to seat back videos .
Try the major consolidaters in the UK for Thai special fares and check prices , i found a difference of nearly £65 for the same ticket and dates
