I have been banned a lot and am currently from the Rumours and News section on Pprune, any Mod should be able to confirm that for you.
Now if the interviewers did a follow up on your answers at the interview and they found an obvious lie - is it possible that they will keep you on the short list?
Or another is they give you a number to call that will give you an upgrade to Business Class on your return flight. What do you now do?
34R had the correct response in my opinion.
