Best Flight Routes to Travel to UK from Hawaii
There are no nonstop flights from Hawaii to the United Kingdom. Travelers from Honolulu (HNL) connect through West Coast hubs, most commonly Los Angeles (LAX) or San Francisco (SFO), before continuing to London Heathrow (LHR). Total travel time ranges from 16 to 18 hours depending on the layover. The first leg from HNL to LAX takes about 5.5 hours, followed by a 10 to 11 hour transatlantic flight. Booking the connection as a single itinerary ensures baggage is transferred automatically and provides protection if flights are delayed.
| Route | Airlines | Flight Time |
|---|---|---|
| HNL → LHR (London Heathrow) | Various (connecting flights) | See details above |
Money-saving tips: Book 3 to 5 months ahead for the best fares. Midweek departures (Tuesday and Wednesday) typically cost $50 to $150 less than weekend flights. Use fare comparison tools and set alerts for price drops on your preferred route.

Time Zone Difference: Hawaii vs. London
Hawaii is in the Hawaii-Aleutian Time zone, which is 10 hours behind London (Greenwich Mean Time). During British Summer Time (late March through late October), the gap may shift by one hour depending on daylight saving transitions in both countries.
Jet Lag Tips for Hawaii Travelers
- Start adjusting early: Shift your sleep schedule 30 to 60 minutes earlier each night for 3 to 4 days before departure.
- Stay hydrated: Drink plenty of water during your flight and avoid excessive caffeine or alcohol.
- Get sunlight: Exposure to morning sunlight in London helps reset your circadian rhythm faster.
- Power through day one: Resist the urge to nap when you arrive. Stay active until at least 9 PM local time.
- Use melatonin strategically: A low dose (0.5 to 3 mg) taken at UK bedtime can help your body adjust within 2 to 3 days.
