FAQs for booking flights from London to Ottawa

  • Can I take a direct flight between London airports and Ottawa Airport?

    Unfortunately you cannot fly directly between these two cities, but there are plenty of indirect routes you can take that only require one stop. You can fly, for example, with WestJet from London Gatwick Airport, which requires a transfer at Toronto Pearson International first. Alternatively, you could fly from Heathrow Airport with Air Canada, which also has a change in Toronto.

  • Can I fast track through security at London airports?

    If you are going to be in a rush at the airport, or should you be travelling at peak times, there is always the option to fast track through security.

For flights from Heathrow, it costs approximately £12.50 to fast track through security.

  • Can I change my currency at London airports?

    Once you have arrived at London airports for your flight, you can use currency exchange bureaus to change your money to Canadian Dollars. If you fly with Air Canada from Heathrow, you will most likely depart from Terminal 2, so you can access the Travelex bureaus and ATMs. From other airports with indirect flights, you can use an International Currency Exchange store or ATM. These are situated prominently in the terminals, so they will be easy to find.

Top tips for finding a cheap flight from London to Ottawa

  • There are two airports in London that serve the route to Ottawa International Airport (YOW) with one stop. With London Heathrow (LHR) being located so centrally, it makes it very convenient for those travelling on business. Whereas Gatwick is great for those coming from the south of London.
  • Save time on the day of your flight by staying in an airport hotel the night before. If you're flying with Air Canada from Heathrow, then you can opt for a hotel such as Aerotel, which is only a short walk from Terminal 2. At Gatwick you could stay at Hilton, which is also close to the terminal building.

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Not full, so lots of room, which is really the only thing that can make flying economy more comfortable. Direct to Toronto is great! I didn't eat or use the entertainment.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Not much food available, not able to choose seats to be near each other, tv did not work

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

Catering strike impacted food service. Snacks & water were available. Gate staff did advise "if you want food on the plane you will need to bring it aboard". Entertainment system not available on this flight. Boarding was early. Departure was early & arrival was early.

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours
