Thomas got a one way vacation. I don' see how airline ticket and hotel reservations are tainted. I think they wanted Justine (for Bianca) and him gone or dead, the message is go away, don't come back and we want your tasty girlfriend. I have no idea what Mavra got. You don't give away major gifts away without them meaning something. Harry got a tombstone and cemetary plot because they were letting him know he will die shortly. Mr Ferro got a major gift and even he was impressed. It means something like he won't intervene against the RC or Black Council or something like that or he owes them a favor.
With the exception of Mr. Ferro, every gift was meant to create a disturbance or doubt within the receiver. Lea got hit hard; because she is big power. Harry has looked at his tombstone and questioned his actions. Thomas and the ticket was the easy way out that he tried to take too late.
