Air India - ZA241 (LN 72, VT-ANM) - so far had 5 test flights and may have one more before being delivered
Hainan - 2 787 from Charleston - ZA431 (LN 76, B-2722) & ZA433 (LN 81, B-2723) pending certification and customer test flights
China Southern - ZA380 (LN 34, B-2725) pending certification and customer test flights
JAL - ZA184 (LN 89, JA830A) had three test flights thus far, may have one more to do
Thomson Airways - ZA317 (LN 92, G-TUIA) - Thomson's first 787 has had 5 test flights thus far.
These six together with the two already delivered would allow Boeing to claim 8 deliveries in May which would be a very healthy re-start to deliveries after three and a half months of growing inventory at Everett and Charleston.
