1. Have you included the Y+ surcharge in the calculation?
2. The only TG flights with Y+ that I've found (not that I'm that experienced when it comes to TG!!

) were the BKK-LAX and BKK-JFK "ultra long hauls".. on the A345.. so that isn't going to help much.. Sorry!
3. I'm going to (happily) spend the night in SIN (before going on to MNL in my case) in order to fly the 380 again...(Does Y get any better than the UD on the whale?)

.. but I see your point!!
