please help me improve my itinerary for january/february 2018 (5 nights in sin and 5 nights in koh samui) for 4 people (2 toddlers so 1 stop is max and less travel time is always preferred). business/first is preferred but not essential. i have the following miles: UR - 800k MR - 40k SPG - 100k AA - 500k i was thinking of flying: option 1 - korean air LAX-SIN round trip - then fly silk air SIN-USM for 25k round trip (singapore airlines miles). i'm not a big fan of having separate tickets cause i'm terrified that there will be a delay and i'll miss the connecting flight. option 2 - singapore air LAX-SIN-USM one way - return leg??? i've done simple searches on united and singapore airlines and the 10+ hours of layover or 2+ stops won't work. i'm sure there are lots of people smarter than me that can figure this out. please help!
