I'm looking into meeting up with my husband in Orlando in a few weeks. He would be landing at 12:09 pm from ATL. I could take either of these flights from SYR and land at 12:09 as well.
Should I go for an extra hour of sleep or should I go with the safer bet.

Sounds like 43 minutes would be enough. What do you think? Oh, this would be a Thursday morning, FWIW.
Lv SYR 7:20 am
Arr JFK 8:32 am
Lv JFK 9:15 am
or
Lv SYR 6:00 am
Arr JFK 7:09 am
Lv JFK 9:15 am
BTW, has anyone been to the website lately? They now tell you how many flights left at that price on some of the flights.
