London Mumbai

Heathrow (LHR) — Chhatrapati Shivaji Maharaj (BOM)

Eastbound

Distance: 7,195 km
Duration: 9h
TZ shift: 4.5h east
Best side: left

Overview

London Heathrow to Mumbai — one of the busiest UK-India corridors and a flagship route for Air India. Overnight, moderate jet lag; aircraft choice is the easiest comfort lever.

Jet lag

4.5-hour eastward shift on an overnight. Sleep the back half of the flight aligned to Mumbai night; get morning light on arrival; expect to feel reasonable by day 2.

Estimated recovery

Without intervention ~5 days

With timed light + melatonin ~3 days

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

Best window side

Eastbound overnight from London — the left side avoids direct sun if you wake mid-flight as you cross the Middle East at first light.

Typical economy row (3-3-3)

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

Air India's A350-1000 and BA's 787-9 are notably easier on the cabin atmosphere than 777-300ER on a 9-hour eastbound. Worth filtering by aircraft.

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.
