Can anyone give me a good reason as to why I shouldn't piece together my itinerary based on 1-way flights? The scenario is as follows.
I am flying UK-Osaka(overland)Tokyo-Bali-NZ-Fiji-Australia-Dubai-UK this summer. I can put this together myself for a much cheaper cost (and I'm talking £500 minimum) than any travel agent is quoting me, however it is obviously a piecemeal route picked together from budget airlines such as Air Asia, Jetstar (besides getting to Japan and getting back from Australia which will be with Emirates).
Should I anticipate any problems in doing this? I am flying directly between places and don't require any transit visas so I don't see a problem there. I've been on a similar trip using an itinerary put together by a major travel agent before but nobody ever asked me a thing at immigration or customs, no proof of onward travel etc but even this is by the by as I will have all my onward travel tickets already purchased anyway to show them.
I'm just trying to clarify whether there is any reason I haven't considered which means I'd be dumb to do this myself as obviously in this particular circumstance it works out cheaper to do it myself, perhaps because it is quite an awkward itinerary.
