Arrival times are at the gate - not landing. That's the time stamp they will use. You can check exact arrival times on several websites - and on expertflyer it will give you additional notes. If you give details someone here can look it up. If VS just look it up on the BA site. If Thomas Cook be prepared to fight.

FYI - If it was the VS flight yester it officially arrived at 11:14am so 3.14 late. But - on a long flight (over 3500 Kms) the delay has to be over 4 hrs to be eligible for full comp. My understanding is that your delay would be 50% if 600eu.
