Ryanair pilots do the flights, there. I thought I had already answered Smith's question because as I said 'Ryanair pay for nothing'
Just in case you are still unable to comprehend, I repeat, Ryanair pilots do the delivery flights. They go to Dublin where Ryanair then remove expensive equipment and send it back to Boeing as it is considered superfluous to a safe operation before the airframe is put on the line. Happy now?
