Good Morning FDOS_UK.
Thank you for your quick reply. On arrival in YYZ, the flight was still over 120 mins late. Westbound one encounters headwinds, and unfortunately the Captain said that he had not been able to make up any time.
I will certainly follow up on the leads which you have supplied, but as you wrote, it is a matter of defining the leglity of the situationn
Thank you again.
