we embarked in Manchester 2 weeks ago heading for Barcelona, kit was Jet2, the flight took off I was at the Port window seat, after a while I was looking out of the window and noticed a small area the size about an Inch on the top of the engine cowling, we had the same plane on our return & was seated in the same paid seats, I emailed Jet2 with my observation & did not make a big issue of it as there was numerous other Rivets all around the Cowling but thought I would mention this, 2 emails later no response, I until now thought Jet2 was a very good airline but after this issue I wonder.
Hop, I was not expecting anything in return for my concern, but just a short email to say we have looked into this would have been enough, but there we go. Az-1, I do have the flight number but not at hand, sorry for my delayed response.
