Train/Airport qiestion

Hi all. I am staying in Liverpool Sunday night but have a flight from Manchester to Ireland at 12 noon on Monday. I have booked a West Midlands railway ticket from Liverpool Lime to Manchester airport via Victoria. It leaves Liverpool Lime at 7:54 am and is due at the airport at 9:09 am. Is this time enough to make the flight at 12 noon? I understand Monday is a bank holiday so would this affect the train at all? Thanks in advance!
