Overview

Amsterdam Schiphol to JFK — the main KLM/Delta transatlantic anchor. Westbound and short enough that aircraft type matters less than seat and pre-flight rest.

Jet lag

6-hour westward delay. Stay up until local bedtime, get afternoon light in New York, recovery is typically 2-3 days.

Estimated recovery

Without intervention ~4 days
With timed light + melatonin ~2 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 daytime — the right (north) side avoids direct sun for most of cruise. For sleep, the window matters more than the side.

Typical economy row (3-3-3)

Left

Middle

Best · Right

The right 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

KLM/Delta 787-9 is the comfort pick if you can choose. A330-300 is decent. 777-300ER is the driest of the three on this 8-9 hour sector.

Expected cabin humidity at cruise

This route's typical aircraft ~15-20%
Indoor air at home ~40-60%

Composite-fuselage aircraft (787, A350) run higher humidity than older aluminum-fuselage types. See what the 787 actually fixes.
