Quick answer: to survive a long-haul flight from Canada to India or Asia, choose your seat early, start shifting your sleep schedule a few days before departure, drink water steadily and limit alcohol, move every hour or two, pack a small comfort kit in your carry-on, and adjust to local time the moment you board. Book connections with generous layovers, and plan an easy first day at your destination.
Flights from Toronto, Montreal, Calgary or Vancouver to Delhi, Mumbai, Tokyo, Bangkok, Singapore or Bali are among the longest journeys Canadian travellers take. Depending on the route and connections, total travel time can range from about 13 hours for a direct flight across the Pacific to well over 24 hours door to door with a layover. Getting through that in good shape is mostly a matter of preparation. This guide gathers the practical strategies that experienced travellers use.
Before you book: choosing the right itinerary
Direct flight or one stop?
A direct flight is the shortest total travel time, but it means one very long stretch in the air. A one-stop itinerary breaks the journey in two, which some travellers find easier on the body, especially older passengers or families with children. If you connect, the layover city can matter: some hubs have lounges, hotels inside the terminal, showers and quiet zones that make a long stopover far more pleasant.
Layover length
Very short connections save time on paper but carry real risk on long-haul routes, where a delay on the first flight can cause a missed connection. As a rule of thumb, look for at least two to three hours on international connections, and more if you change terminals or must clear security again. If you book separate tickets on different airlines, allow much more time, because the second airline has no obligation to rebook you if the first one is late.
Departure time
Overnight departures from Canada often work best for sleep, because your body is already tired and the cabin lights are dimmed for a long period. Departures that arrive in the early morning at your destination let you push through to a local bedtime, which speeds up jet lag recovery.

Choosing the best seat for a long flight
- Window seat: best for sleeping, because you can lean against the wall and nobody climbs over you.
- Aisle seat: best if you want to get up often to stretch or use the washroom without disturbing others.
- Bulkhead and exit rows: more legroom, but armrests may not lift, and bassinet positions near bulkheads can mean crying babies.
- Avoid the last rows: they are often near washrooms and galleys, with more noise and traffic.
- Couples: in a 2-4-2 or 3-3-3 layout, booking the aisle and window with the middle empty sometimes leaves the middle free on less busy flights.
Select seats as early as your fare allows. On long routes, it is often worth paying for seat selection or a premium economy upgrade if your budget permits, since the extra recline and legroom make a measurable difference over 14 hours.
Preparing your body in the days before departure
Jet lag between Canada and Asia is severe because the time difference is huge, often 9 to 13 hours or more. You can soften the blow by shifting your schedule gradually:
- Three to four days before: move bedtime and wake time by about an hour per day in the direction of your destination.
- Get daylight at the right times: morning light helps you shift earlier, evening light helps you shift later.
- Arrive rested: avoid a late night of packing before an early flight. Pack two days ahead.
- Eat lightly: heavy, salty meals before and during the flight increase bloating and discomfort.
What to pack in your carry-on
A small, well-organised comfort kit is the single best investment for a long flight:
- Neck pillow that actually supports your head, not just a decorative one.
- Eye mask and earplugs, or noise-cancelling headphones.
- Compression socks to support circulation in your legs.
- Refillable water bottle, empty through security and filled afterwards.
- Lip balm, moisturiser and saline nasal spray for the very dry cabin air.
- Toothbrush, toothpaste and face wipes to feel fresh before landing.
- A warm layer or scarf, since cabins can get cold.
- Prescription medication in original packaging, with enough for possible delays.
- Charging cables, a power bank that meets airline rules, and downloaded entertainment.
- A change of clothes in case your checked bag is delayed.
Remember liquid limits for carry-on bags in Canada and at transit airports. Check the latest rules from the Canadian Air Transport Security Authority before packing.
During the flight: staying comfortable
Set your watch to destination time
As soon as you board, switch your phone and watch to your destination’s time zone and start living by it. Sleep when it is night there and stay awake when it is day, even if that means watching a film when you would rather nap.
Hydrate steadily
Cabin air is very dry. Sip water regularly rather than drinking a lot at once, and ask the crew for refills. Alcohol and caffeine both dehydrate and disrupt sleep, so keep them modest.
Move regularly
Long periods of sitting increase the risk of swelling and, for some people, blood clots. Get up every hour or two when the seatbelt sign is off, walk the aisle, and do simple seated exercises: ankle circles, calf raises and knee lifts. People with a history of clotting problems should talk to a doctor before travel.
Sleep smarter
- Recline your seat, use your pillow and eye mask, and fasten your seatbelt over your blanket so crew do not wake you.
- Dim your screen and avoid scrolling right before trying to sleep.
- If you consider sleep aids, discuss them with a health professional before your trip and never try one for the first time in the air.
Eat with intention
Pre-order a special meal if you have dietary needs. Many travellers find that eating lighter, and timing meals to the destination’s meal times, helps their body clock adjust.
Travelling with children on long flights
- Request a bassinet early if you are flying with an infant, as they are limited.
- Bring new small toys or activities to unwrap during the flight.
- Pack extra clothes for both children and parents.
- Feed or offer a drink during take-off and landing to help with ear pressure.
- Accept that sleep schedules will be imperfect and plan a gentle first day.

Making the most of a long layover
A long layover can be a chance to rest rather than a chore. Look into airport lounges with day passes, showers or transit hotels inside the terminal. If you plan to leave the airport, check the entry rules for that country, since some require a visa or electronic authorisation even for a short visit, and always leave plenty of time to return through security. If your connection is overnight, a hotel near the airport can be worth booking in advance.
Arriving: beating jet lag in the first 48 hours
- Get outside in daylight on your first day. Natural light is the strongest signal for your body clock.
- Stay up until a local bedtime, even if you need a short nap of no more than 20 to 30 minutes in the afternoon.
- Eat meals at local times.
- Plan a light first day: leave major sightseeing and long drives for day two or three.
- Book a hotel that allows early check-in or reserve the room from the previous night so it is ready when you land in the morning.
That last point makes a huge difference when flights arrive at dawn. Our guide on hotel booking mistakes covers check-in times and other details that catch travellers out.
Health considerations before a long trip
Visit a travel health clinic several weeks before departure to review vaccinations and medications recommended for your destination. The Government of Canada travel health page lists general guidance, and destination pages describe specific risks. Carry a copy of your prescriptions and make sure your travel insurance includes medical coverage abroad.
Common long-haul mistakes to avoid
- Booking a tight connection on separate tickets.
- Drinking alcohol to help sleep, which tends to worsen sleep quality and dehydration.
- Wearing tight clothing or new shoes, as feet often swell during long flights.
- Keeping essential medication in checked baggage.
- Scheduling an important activity on the afternoon you land.
- Forgetting to check visa or electronic travel authorisation requirements for the destination and for transit countries.
