In Ryanair world all our flight plans now have all FIR Boundary points underlined on the plog and elapsed time to each one.
Also SOP is to put said Boundary point in the fix page in the FMC so it has a green ring around it on ND.
Also if we get to said boundary and no said frequency change then we challenge ATC.
Ryanair worked out a while ago flying in formation with fast jets and picture in the Daily Mail is not good
PR.
