Departure: Seattle-Tacoma International Airport (SEA)

Flights from Seattle to London leave from Seattle-Tacoma International Airport (SEA), serving Seattle - seattle is the Pacific Northwest city of the Space Needle and Pike Place Market, with Mount Rainier on the horizon. Plan to be at the airport about two hours before an international departure and ninety minutes before a domestic one; earlier at peak times. Online check-in opens 24 to 48 hours before and we send the link with your ticket. Getting to the airport: The Link light rail runs from the airport to downtown in about 40 minutes and suits a central hotel with light luggage; for the Eastside, cruise piers, Mount Rainier, Leavenworth or the Olympic Peninsula, a private car from the terminal is faster and simpler.

• Ask us about the terminal and fast-track options at Seattle-Tacoma International Airport
• Arrive about 2 hours before an international departure, 90 minutes before a domestic one
• Online check-in opens 24-48 hours before; we send the link and the booking reference
• Keep the passport or ID used for booking with the e-ticket - names must match exactly

Arrival: London Heathrow Airport (LHR) and getting into London

You arrive at London Heathrow Airport (LHR). The Elizabeth line and Heathrow Express, the Gatwick Express, the Stansted Express and the Luton train are all fast to a central station; from there the Tube with suitcases means stairs, gaps and crowds, and Wembley, Windsor or an Oxford Street hotel each add a change, which is why families and groups book a car from the terminal door. If you would rather not think about it, we book a private transfer from the airport to your hotel in London, with the driver tracking the flight in case it is late.

Many travellers continue from London to somewhere else. We provide those tickets too, so one WhatsApp conversation covers the whole itinerary.

Baggage, seats and classes on the Seattle to London flight

Baggage is the item that most frequently changes the real cost of a flight from Seattle to London. Full-service fares normally include a checked bag and a cabin bag; low-cost fares start with a small cabin bag and add the rest. We tell you the allowance of the fare we send, and whether adding a suitcase at booking is cheaper than at the airport (it almost always is). Seats can be selected on most airlines for a fee or free at check-in; in economy and business the differences are space, meals and flexibility.

• Adding baggage at booking is cheaper than at the airport - we add it for you
• Seat selection free or paid depending on the airline; families seated together on request
• Infants under two travel on a lap at a reduced fare; children have their own seat and fare
• Meals included on full-service airlines; special meals ordered in advance on request

Flying with children, families and groups from Seattle to London

Travelling with children? Put the ages on the form: infants and children have different fares and different baggage allowances, and we apply both. Groups - a company, a school, a wedding party - are booked together so everyone sits in the same section and one confirmation covers the whole party. Haqqi Tours also provides the minivans and Sprinters that carry a group between the airport and the hotel at both ends.

Things to do in London when you land

Buckingham Palace and the Changing of the Guard, the Tower of London and Tower Bridge, the British Museum, Big Ben and Westminster Abbey and the London Eye and the South Bank are what most passengers come to London for. London is served by more airports than any city in the world: Heathrow (LHR) about 25 km west of the centre, Gatwick (LGW) about 45 km south, Stansted (STN) about 60 km north-east, Luton (LTN) about 55 km north and London City close to Canary Wharf; the West End, the City, Westminster and Kensington form the centre, with Windsor, Oxford and Cambridge within reach by road. Eat a full English breakfast, afternoon tea and a Sunday roast in a pub while you are there.

If you want the days in London organised - a driver, a guide, timed entry tickets - we do that too. Mention it through WhatsApp.

Best time to fly from Seattle to London

Flights from Seattle to London run all year, 2-3 a day. London is busy all year, with summer, the Christmas lights and the January sales at the peak; the M4 from Heathrow, the M23 from Gatwick and the M1 from Luton are slowest at weekday rush hours, and a Sunday evening back into town. If you can travel outside those weeks the same seat costs less and the airports are quieter. Whatever the month, early booking is the single biggest saving.

Return flight from London to Seattle

The London to Seattle flight is the same route in reverse, about 9 hours 20 minutes. Haqqi Tours offers the return ticket in the same conversation; if you are not yet sure of the return date, we can book a flexible outbound or wait, and explain which is cheaper.

How much is a flight from Seattle to London?

"How much is the Seattle to London flight?" is the question we get most, and the honest answer is that it moves every day. Low fares open months ahead and disappear as seats sell; peak seasons, school holidays and the most convenient departure times cost more; a fare with a checked bag and a flexible ticket cost more than a hand-luggage-only seat. Haqqi Tours arranges the current cost for your travel date quickly of receiving the form - the actual fare, not an estimate.

Ask us for two or three options and we send the cost of each - for example the cheapest fare with hand luggage only, the same flight with a checked bag, and the best-timed departure of the day - so the comparison is in front of you before you book.

Cheapest flight from Seattle to London: how to pay less

A cheap Seattle to London flight ticket is rarely luck. It is the right airline, the right day and the right fare class - which is what we check for you:

• Consider early-morning and late-evening departures, which frequently carry the lowest fares
• Let us know if your dates are flexible - moving by a day can change the fare a lot
• Pack to the fare: a hand-luggage-only ticket is cheaper if you do not need a checked bag
• Compare airlines - on this route the cheapest carrier changes from day to day
• Book both directions together when a return fare is cheaper than two singles, which we look up
• Ask about infant and child fares and about group bookings for four or more

When you fill out the form, mention if you can move your dates. We scan the fares around them and send the cheapest Seattle to London flight first, then the alternatives.
