Seat 2a:
Great report!
I lauged out loud reading about your ailing cabin mate on the CX flight.
On a SFO-LHR BA flight, a very famous British director and I were the only ones in FC, both in row 2. I swear to GOD that he couged the ENTIRE way to London! After a while I moved to 4K to get a good night's sleep. It does make you think twice about all the reports of or poor air inside an airplane!
I look forward to hearing of your future adventures!
