Options you have:
1) Book SQ SIN - JFK, LAX - SIN, then price out your internal flights (JFK - LAS, optional LAS - LAX, if you decide to drive).
2) NH can also include domestic flights on UA, so might be slightly cheaper
3) SQ SIN - LAX round trip, then book domestic flights.
True.
It is. One should check
ITA Matrix first
Makes no sense. Flights originated from SIN would cost him $5K in Economy for the RTW fare. Checked today.
Affirmative. But options are available. I'd suggest to fly with ANA to JFK and from JFK/LGA/EWR fly to LAS using southwest/jetblue/virgin america. It shoudl cost less than SIN $2.5k for both roundtrip flights.
have tried this ita matrix and try out a few combi yesterday on a few airlines;
travel dates: 20th dec - 3rd jan
1) sin - nyc, nyc - tokyo (stopover tokyo) - sin.
ana & sq = ~3.1k, jal = ~3.4k
- haven add domestic from nyc - las - nyc
2) sin - lax/sfo, lax/sfo - tokyo (stopover tokyo) - sin
ana = ~2.3k, jal = ~2.7k, sq = ~2.9k
haven add domestic from lax/sfo - nyc , nyc - las, las - lax/sfo
3) sin - las, las - tokyo (stopover tokyo) - sin
ana = ~3.1k, jal = ~2.7k, sq = ~8k (zzzzz, so exp)
haven add domestic from las - nyc - las
4) sin - nyc, sfo/lax - tokyo (stopover tokyo) - sin
ana, jal & sq = ~3k
haven add domestic from nyc - las - sfo/lax
5) sin - nyc, las - tokyo (stopover tokyo) - sin
ana = ~3.3k, sq = ~9k, jal = ~2.6k (cheapest liao)
haven add domestic from nyc - las
item 5 is the cheapest of the lot so far, if add domestic it should add up to borderline 3k all in. any comments, pls?
