Do you think there will be one more aircraft in the London bases if pay there is lets say 5% more than de regional bases and 20% more than the european bases? We will see ORY guys flying ORY-NCE/ NCE-LGW-NCE/NCE-ORY, same for TLS, LIN,... SXf guys will do the LTN-AGP, MAD, BCN,... Scottish based crews will operate through STN and so on... And if the LODON based fo's want a command they can transfer to the base of their choice at the local salary of course... So if you accept the different salaries dont forget to ask a descent staff travel in return!
