It is possible book and fly LAX-LHR-MAN as round trip, but drop the first leg of the return and pick up the flight at LHR-LAX. I guess the answer will be no but could it not be argued that a person was stuck in Birmingham (or wherever) on the morning of the flight and it was quicker and easier to take a cab straight to LHR rather than risk a run to MAN? Thanks in advance for your thoughts on this.
