Overview

Athens to JFK — westbound transatlantic, daytime flight. Westward direction is the easier of the two on the body — you delay sleep rather than advance it, which the human circadian system does naturally.

Jet lag

7-hour westward delay. Easier than equivalent eastward. Stay up late on arrival day, get afternoon light, expect to feel functional within 2-3 days.

Estimated recovery

Without intervention ~5 days
With timed light + melatonin ~3 days

Estimates only — based on ~1 day per time zone west, compressed roughly 40% with a timed protocol. See how long jet lag actually lasts .

Best window side

Westbound day flights — left side avoids direct sun for the bulk of cruise across the Atlantic.

Typical economy row (3-3-3)

Best · Left

Middle

Right

The left window is the calmer pick on this route. For sleep, the window itself matters more than the side — see how to sleep on a long-haul. For the exact rows and seat letters on this aircraft, use the seat picker.

Cabin atmosphere

777 and older A330 are dry — bring saline spray. 767 is the worst for cabin humidity on this route.

Expected cabin humidity at cruise

This route's typical aircraft ~4-10%
Indoor air at home ~40-60%

Older aluminum-fuselage aircraft (777, A330, 747) run drier than composite types like the 787 and A350.
