Joleb, I have to agree with you on that......
However one has top remember that the gap between F and J are getting closer and closer. I just did SQ220, a flight in the past that was packed in F everytime I fly this route, but today only 3 passengers in F, while J, as always, is packed with only 10 seats left.
I think airlines won't be stupid to remove F if it gains a promising profit, and obviously enough, the importance of F is declining after introduction of beds in J. The main difference that J can never beat F is the privacy and comfortness that the cabin provides, which to a lot of people, is not worth paying for that extra money just for that privateness!
would have no competetion for now on the SIN
non-stop route. For passengers who insist in flying F, they could always choose the other flight that goes via Narita, while J passengers could have another option. Afterall if people are willing to pay for flying in F, they probably won't mind the extra 2-3 hours of flighttime!
