I'm planning a Europe trip with my fiance and we're interested in booking our flights from and returning to the same city (Brisbane, Australia) but arriving in London and then departing from Rome - which we'll make our own way to from London.
I'm wondering if there is anything to keep in mind when booking tickets this way, will it cause any problems with customs/borders? Does it have to be with the same airline for any reason?
We're booking this all ourselves, no travel agent and it's our first time going to Europe; I really just want to make sure there's no reason not to do this or if there's anything I haven't thought of.
