Skyvvards Thank you for reminding me of the wonders of a first trip in Business Class. Flying is an amazing privilege and we are lucky to be able to experience it.
Please don't let some peoples' comments dampen your enthusiasm.
That being said, as with all travel experiences, I suggest to assuage one's expectations in order to best enjoy the experience. Your questions are excellent and there is a great number of people on FT who will offer suggestions to maximise the trip.
Enjoy!
