While Rob and Amber are in the same clothes, and the seats look very similar (color and possible pattern), and ROb & Amber are seated on the same side of the plane.
In this shot (the one for this episode?), One of the Cha's (who is the taller thinner one Oswald?), is wearing what appears to be a white tea shirt.
In the first part of the first episode (to airport on plane, out of airport and to Pim's) he is wearing no white under shirt/tea shirt. But it is the clothes he wore for the next day in checking in to the Hacienda (well at elast a white tea shirt there.
So I vote a new shot of a different flight.
