Well, up until March this year, JL also had F service between NRT and CGK. You will have a great flying experience with GA F, enjoy! 7 hours is definitely not long enough to enjoy its great service. Do report back on your experience if you don't mind.
Will do. So far I'm not impressed with the pre-flight service. I had a couple simple enough requests and none were honored. I responded asking for L pajamas but asking to have XL available too just in case the size doesn't fit—and they said no! What kind of airline doesn't have every option available onboard for its passengers? They also denied me the car service and another thing I asked for.
This is on a paid ticket, not on the 90% promo or an award!
