is this a daily service?

Do you mean the LHR MAN LHR being on the 767?

The Shuttle, as it was once branded, to LHR is usually on 319/320/321, however when the MAN JFK MAN 767 aircraft needs to be changed over the replacement aircraft comes up on the first LHR MAN departure, the crew then swap the aircraft with the one that has just arrived from JFK for the return to LHR.

On that day the aircraft was late in from JFK causing a one hour delay to our 0815 departure to LHR.

Does that answer your question?
