Thank you so much again guys for the help , and I did fear that it would differ from operator to operator - probably why I found it so hard to get a definite answer online.
I don't want to come across as someone being lazy and just trying to seek answers here , but I rather exhaust all information online before seeking clarity so many thanks and hope I am coming across in the right manner.
Operator specific I suppose I would be most interested in Ryanair so not sure if @172driver or @ManaAdaSystem you are working for the forementioned.
Kind Regards,
SAR
