So I have been playing with a number of mixed free ones for a number of flights. I am based in BOS and I have a UA 1 way to LIM for next christmas. I am looking to book LIM-JFK(stop)-LAX-KOA on LAN/AA I am figuring that I would be booking BOS-JFK r/t with avios and call it a day, but I was starting to wonder about crazy ideas. Can I potentially have two simulatious stop overs? If for example I have NRT-BOS booked right now. If I had booked that NRT-BOS(3/2014)-(stop)-(2/2015)PUJ and then also booked the LIM-JFK(1/2015)(stop)-LAX(3/2015)-KOA is that valid or does it violate contract of carriage?
