no contest at all, I'm sure your combination is much more complicated as I was mostly just following your tips (saw MEL-SCL-MAD-NRT for 500€ months ago but never even thought about routing it over PPT, IPC and GPS before your tips, thx again). For me personally this 8 leg itinerary on 1 ticket is a personal record (and on the limit of my knowledge), for you and many other more experienced MRers it is sure just a normal thing
And thx for PL tips, very appreciated.
