Today I noticed that Delta Airlines is offering a great sale on travel between Houston and Tokyo. The timeframe is for my favorite season to visit Japan, late October and early November. The cost of the flight is $611.16. It is one of the shorter flights at around 16 hours, with only an hour layover in Minneapolis. It is a great price and I wish that I could take advantage of it myself.
The only negative that I can find is that Delta does not offer an upgrade to economy, like economy plus or economy comfort. That extra 5 or 6 inches of legroom is worth every penny. The upcharge seems to average about $5 to $10 per flight hour. Anyway, the price is so good that I think that I would have no problem toughing it out for the thrill to go back to Japan!
