I use the LHR – BKK – LHR route regularly. I used to fly with EVA but to be honest I never like the bed in Business class. Also the return flight time was no good to me.
So it was a choice between Thai and BA and I chose BA.
Since they stopped the onward leg to SYD it has been a dream using miles for upgrades, before that it was virtually impossible. Unfortunately with the planned flight timings changes in Oct it looks like I will be looking for another carrier that leaves LHR in the evening otherwise I will be obliged to overnight at LHR on the outward leg and BKK for the return as I live in UTH. Any suggestions appreciated.
Apologies for going off topic a bit.
