well as i now have recovered form the 31st i have been looking into this trip a little more from what i have gathered that i can go through the US twice providing that one time is for transiting ie less than 24hrs is like right?

also dublin is an expensive place to get a ONE ticket and if i say in europe gibraltar is about the cheapest to start the trip

therefore to cut cost would the follow itinerary be possible

GIG-DUB(via london)-LAX-MEL-SYD-HKG-LAX-DUB
or something like than or if you guys can come up with a better routing but this would see well into OW saphire and would leave me in a good position to make emerald
