Flights to Glasgow

I booked flights for Mom and myself, to Glasgow, leaving November 7 on flight AC898 to London, then changing to AC6625 at Heathrow, to Glasgow. Flight leaves Edmonton at 17:45. Then the return flight is on November 21, flight AC6666 to Heathrow and then on flight AC899 to Edmonton. Flight lands in Edmonton at 13:15. I took the flight to Glasgow, so I could get a direct flight to London, and then direct from London to Edmonton instead of having to change planes.
