That is more analogue to changing rolls of film than a 'proper' jump-cut. I had not seen anything like the cuts of going from the party back to the airport before; though I would much like to see a game which has done it.
Yes, the more I think about it the more I realise you are right. I'm sure there must be some games that have jumped from one time/location to another without a loading screen (although I can't think of any off the top of my head) but they always clearly signpost it as a transition with either a loading screen or some sort of "screen effects", it has a very different feel to it.
Boldness.
Well, that seems reasonable for this case
