My wife and I are looking at traveling to Japan in May/June of 2022 for a couple of weeks. We are starting to see some flights from either AUS, DFW or IAH to Tokyo for $3500-4000 each RT on various airlines. Would these be considered a good deal now or would waiting for something lower be even better? We've flown business class to Europe before and understand that market, but we just aren't sure what a good price is flying business class to Asia.
