commercial flight fuel charge increase to RM2k+ for return
choose AA better

I almost can confirm, budget airlines no longer land at Haneda anymore.
Good & Bad

Good = no longer midnight flight to Tokyo
Bad = far away from Tokyo City.

there are 2 good offer to go Japan now....

One is Via Scoot, midnight ride to Jap......come back via AA
All in all, ~RM1000 + ~RM1000 = about RM2000 round trip. hav to buy 2 times la

Another is via Manila Air, midnight ride to Jap, come back via AA.

btw, anyone now how the transit works for Scoot?
Do i need to pickup and check-in again at SG airport?

I heard that transit ease also....
somehow someone said we need to bring out and bring in from flight to flight....lets hope that is not the case for Scoot transit...

hm....ya..didnt think about that for AA on the come back trip....but is buatan msia...support a bit?

thats interesting, for AA still promote the route

and all they did to warn is to just place a small exclamation mark on the route selected, if no hover over cant see

means that they can reroute to NRT instead 
** but since philippines airlines also not part of any alliance like the one u mentioned

yet they also offered HND as their route on top of NRT (verified via their FB post as well)

does that mean that they might reroute too?

This depends how much time you going spend in Japan and how much homework you doing. If you just got a week to spend in Tokyo, you can skip Yokohama.
