ruleIf the AMS connection feels tight when you land, default to A — don't gamble on the food run and miss boarding.

On arrival · Fri SF ~12:00

  • Stay up until 21:00–22:00 SF. This is the whole game.
  • Get outside in daylight through the afternoon (June SF = long light evenings).
  • No long naps. One ≤20–30 min nap before 15:00 only if desperate.
  • Caffeine OK early, cut off ~14:00.
Weekend to finish adjusting before the conference. Westbound is kind — likely feel decent by Sunday.
Pre-trip checklist + why this works
  • 1–2 nights before: bank sleep (sleep a bit earlier) so you survive the ~04:30 wake-up. Don't try to pre-shift later — it fights the early departure.
  • T-30h: online check-in → grab aisle/window (seats are unassigned; matters for 7h of sleep).
  • Why sleep the long leg: AMS takeoff = 00:50 SF, landing 11:45 SF. The flight ≈ a SF night, so sleeping it lands you rested at SF midday with only ~9–10h to hold until SF bedtime. Clean alignment.
  • Melatonin mostly unnecessary westbound; small dose only if you wake at ~04:00 SF and want back down.

C trades airline breakfast for a better meal + the longest sleep — easy given the 5-hour layover.

AMS layover → HEL → home

  • AMS 10:05–15:20 (Finland time): it's "morning" — stay awake, move, daylight, coffee. Build sleep pressure for tonight. ≤30 min nap only if wrecked.
  • AMS→HEL: light snack, stay awake (≤20 min nap max).
  • Land HEL 17:40: don't self-drive Turku — eastbound + post-flight is the dangerous combo. Train or pickup.
  • Home ~20:30: push through to ~22:30, then bed. No evening nap.
Pre-SF prep + adjusting Tue/Wed (the eastbound bit)
  • Last 1–2 days in SF: go to bed & wake earlier — pre-advance toward Finland, even 1–2h helps.
  • Finnish June nights are bright (light till ~23:00+). Evening light delays you — wrong way. Tue evening: dim lights / sunglasses late, blackout or eye mask to sleep.
  • Seek bright light Wed morning — that's what advances your clock home.
  • Melatonin ~1h before bed Tue + Wed nights to re-anchor.
