Narrative:

Embraer jet during flight; visually noticed that the right wing's skin on the trailing edge; where it meets the outboard flaps (approximately inline with the right wing; overwing fuel cap); the skin was separating in flight. It was back to normal after landing and it is undetectable during a walk around. I informed those in charge of the flight but I did not follow up. Aircraft should be inspected for possible systemic; manufacturing; or design issue.
