I wasn't suggesting that there was a direct flight, i just meant that i would take the 2 segment option and book them seperately rather than the 3 segment connecting flights that the booking tool suggests. (did you read the original post?!)
Yes I did, repeatedly. And then I read post #4:
Sounds like I'll just book the HAN-MEX flight as HAN-NRT NRT-MEX
which very clearly says to me that you were hoping to book HAN-MEX as a single flight.
