I think that you need to beware of some on the generalisations made here ... if you will only travel on your own carrier, in a premium cabin and point to point then you will find such travel difficult .. if you have access to ZED fares and are flexible with your travel plans then its far easier. You need to put a bit of effort into planning the trip, decide wher you want to go and look at what interline options are available ... then get advice about loads around specific times and then make the decisions ...
