Cheapest coach fares. For multiple dates out from JFK. September 30th to October 4th for instance. Delta comes out with the best rating with price/time and the lowest price out of JFK airport for this route.

The fare I saw was $1152.70 with all taxes for Economy Class T

The price to Singapore is still high, but compared to all other airlines, it comes in at the lowest. I realize other airlines are somewhat better but not worth the price premium.

Now obviously upgrades on Delta will probably be minimal however. But considering Delta is a safe and reliable carrier, it seems like the way to get to Singapore right now.

Delta must have made scheduling changes to realign with the Singapore connection flight at Narita. I don't recall them having the lowest fare pricing along with excellent flight times coming from JFK to SIN before.

Class T is a non upgradable fare for international and I never meant to say these fares were upgradable. What I was saying however is if you accumulate mileage using these fares, you can either remain in coach and get the best pricing and get award tickets or book another fare code which has the upgrades available so you will still be paying less than a full fare ticket and Delta has the new Lie Flats on these 747's now for the most part.
