As far as Ican see the BA machines start at line number 108.
The terrible teens are a group of early build machines.
Boeing has officially allocated 3 very early build 787s to Transaero Airlines. The three frames are LN 11LN 12 and LN 14. All three were previously going to be delivered to ANA.
ANA has since asked for later built 787s. Boeing still has about 7 more that need to be re-allocated to other airlines. It has been rumored that Transaero would pick up these aircraft from Boeing on the cheap when they closed on the order of 4 787s early last year. It is also rumored that Lion Air will be picking up their 5 aircraft from this block as well.
After travelling on the QR 787 earlier in the year I was very impressed, It will be interesting to see what QR do with the A380, the first of which is in final assembly.
