Flight Deck visits?

[2morrows pilot 2day]

Hey guys,

Will make this quick, as money on the internet cafe is running out fast! (hope this is in the right area too!)

Does anyone know if visits to the flight deck are permitted anymore- i realise this is no longer possible inflight, but how about after landing when the engines are off and disembarking has started?

I would particularly like to know if thomsonfly allow this, as I am flying with them Monday.

Thanks in advance,
