Whilst not necessary out of HK I came across a great deal over the holiday period from LGW to HK which was £10 cheaper than flying business from LGW to BKK. The EK 384 of course stops off at BKK on the way to HK. Was about to book it, when I noticed the companion ticket for First was also £10 cheaper going LGW to HK stopping off in BKK and at exactly the same GBP price as Business. Thought it was an error but able to book it. My wife and I are trying First on the A380 for the first time in early Febuary with a two week stop over in Thailand.
