The AKLJFK sked I see (6Oct22) has the flight dep AKL at 1940 and arrive JFK at 1955. During the northern winter, it arrives JFK at 1740. Both times allow for domestic and international connections.

UA serves upwards of 25+ European destinations nonstop and most major and minor cities along the East Coast from EWR while JFK has no Star Alliance domestic feed (except to SFO and LAX!) and its international Star Alliance flights are limited to the hubs of its European Star partners, some of whom also serve EWR.
