I was looking on ExpertFlyer to see if I could get a cheap one-way fare from TYO to BKK, but TG hasn't announced any discounted fares in any class for the entire month of March and possibly April as well. The only fares I'm pulling up are TG's normal (IATA) fares in all classes and the usual YY fares. I did a search on TG's booking engine, and got similar (i.e. non-discounted) results. Any reason for this that I'm not aware of?
