Thanks for that; I misunderstood what you were saying.
Just as a matter of interest, if your rostering department considers a limo ride from Airfield A to Airfield B to be 2 hours and 25 minutes, where would you be then?
For that matter, what would happen if you got stuck on the M25?
I know the answer already but I am just curious to know how your particular crewing department would deal with the situation and how you would respond.
