fixes #794

this is a proposal based on what I said in the issue

I've not done this, because I don't know how to do this in a simple way:

But I don't know if in this case, we should ensure the integrity of the data and always pick the same airline for both the ticket and its flight. I'm tempted to say "yes", because for me the whole point of this recycle() method would be to ensure integrity of the model. As far as I understand, this would differ from Laravel's recycle() method, where they always pick data randomly from the recycle collection.

By the way, I'm not a huge fan of the name recycle(), and because I'm not sure that we do the same thing than in Laravel, maybe we can change its name? stickTo() or something like that?
