The flight from FLL to EWR should be fine (including take off and landing). The air is very calm and winds are light at both airports.Continental Airlines flight # 400 leaving Fort Lauderdale at 7AM arriving in Newark.
CO15 EWR-HNL on February 1st at 1:20PM
The long flight from EWR to HNL may get light to moderately turbulent at times over the Mountain states, especially over Colorado. This happens a lot with flights in the western united states. Once you clear the mountains however, it looks good, the jetstream is not in your way between the western border of the US and Hawaii. Conditions for this flight are pretty good, so all in all it should be fine.
