Company policy
I am afraid I will have to stand firm on company policy here, smoking is not allowed on-board any EY aircraft at anytime!
Those who are not abiding by this policy are infringing CAA regulation and this issue could certainly be escalated to other relevant authorities and this would affect EY's landing rights and certification.
Again if it has the management's blessing, then someone may have been smoking illegal substances when making this decision and this could also lead to a serious allegation that EY is a company run by unprofessional people and this is absolutely not true!
Yeah!
