Air India 787 to perform at Paris Air Show

This is plain speculation on my part but Boeing may be prepping ZA242 (LN 90, VT-ANN) for Air India to put on a flying display at this years Paris Air Show in mid June.  The aircraft flew to Boeing Field last week then flew a flight on Friday at BOE787.  I believe that this flight was practice flight for an aerial demonstration at the show. Given the flight number it flew under is normally reserved for special marketing flights or for air show flights, I feel that this is strong evidence that this aircraft will by at the Paris Air Show.  If so this aircraft probably won't be delivered to Air India until mid to late June.
