I book all student and staff travel for the FE College I work for, and NEVER make any flight bookings without either a passport scan or driving licence scan (if an internal UK flight).
All bookings are then made using all available full names as on the ID. It is not my job to second guess what anyone's full, preferred or known name is, and this policy has never produced any errors or problems with IDs when flying to any airport, either in the UK, across Europe or worldwide.
Once all passengers understand the consequences if they don't provide a scan, then there are no problems. No scan = no booking = no travel. Simples .......
