They all know about Jet2, trust me...They were having a laugh at your expense and unfortunately you took the bait..
Perhaps you should give JET2_738 the benefit of sufficient intelligence to realise that those posters saying they didn’t know of JET2 are the same ones that have for years denigrated the company bordering on slander and with little else contribution to any other threads. JET2_738’s response was a lesson to us all that the best defence is to pretend ignorance and respond without offence but with tongue in cheek.
Trust me, in your shoes, my next action would be to delete your post and save face.
