Top tips for finding cheap flights to California

  • If you would like to fly from Ottawa to California, Ottawa Macdonald-Cartier International Airport (YOW) will be the best place to start. There are a few airlines that fly from Ottawa to one of the airports in California, such as Los Angeles International Airport (LAX) or San Diego International Airport (SAN).
  • While you will be able to fly from Ottawa to California, there aren’t any direct flights between these two places. More often than not, you will only have to make one stop while you’re on your way to California from Ottawa, but there are instances when you’ll have to make two or even three stops en route to California. Ideally, you’ll want to search for an airline that can get you from Ottawa to California in just one stop, since it could significantly trim your travel time.
  • Flying from Ottawa to California will take you at least 12 hours, in most cases, and sometimes even longer than that. Because of this, you may want to consider booking a first-class ticket for your flight. Before you do, though, you should book an economy ticket and keep your eyes peeled for emails from your airline. It might be willing to extend a discount on a first-class ticket if you’re willing to wait.
  • If you want to avoid getting hit with baggage fees when you arrive at Ottawa Macdonald-Cartier International Airport, you may want to limit the amount of luggage you bring. Airlines like Air Canada will charge you about $30 to check your first bag and $50 for a second one. By only bringing only a carry-on bag, you can save money while you fly to California.
  • It’ll be important for you to head to Ottawa Macdonald-Cartier International Airport about two to three hours before your international flight to California. Once you make your way through security, you can kill extra time by heading to one of the lounges in YOW, such as the Aspire Lounge. It’s open to all passengers regardless of which airlines they’re flying.

Airline reviews

I flew with Porter yesterday and overall had a positive experience. The flight was delayed, but the airline did a good job keeping passengers informed with frequent updates throughout the process. My biggest challenge was actually in Terminal 3, where the speaker system wasn’t very clear. It was often difficult to hear the announcements, which made it harder to follow updates at the gate. On board, the experience improved significantly. The aircraft felt very new and well maintained, and the seats were surprisingly comfortable for a short-haul flight. One of the flight attendants seemed a little disengaged, but the other was excellent—friendly, professional, and a pleasure to interact with. Despite the delay, the comfortable aircraft, clear communication from Porter, and positive onboard service made for a good overall experience.

It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.

Organization and the adjusted times but the snacks could be of a bigger portion

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Lavatories broke with an hour to go. At least we were on time.

Due to mechanical problems it was delayed causing problems the actual flight. Was fune

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

Porter, like most airlines, need to improve their baggage policies. In reality, there are no longer 'cheap flights' because passengers pay exorbitant baggage fees.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.

My flight was delayed by a whole day, so I lost a day of my vacation.

How would you rate my experience when I was stuck in YOW without being offered a cup of water by the airline?

I loved the fact it was on time and it was a smooth flight to my destination.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Absolutely terrible, from the customer service to boarding the plane. On the phone, there was some mishaps with getting in my correct date and they did not help me retrieve a refund or any assistance. I’m gonna be reporting to all my followers and family around the region of Los Angeles to New York.

Nothing to like because my inbound flight was cancelled without notification by West Jet or third party, JustFly. I couldn’t take the inbound flight due to cancellation; therefore could not take the outbound flight back.

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Very good over all , would have been nice to have entertainment on the flight

Absolutely the worst airline I have ever taken. They lost my baggage and told me my bag tags had been cancelled. When my bags arrived days later I had to pick them up at 3:15 am. My return flight was delayed another 6 hours and they broke my bag. Westjet does nothing to try and make it a better customer experience and all the customers services representatives I spoke with were useless and incompetent. Never flying westjet again.

Not a tonne of food for purchase items for early morning.

Long delay die to pet mix up. Also bags took forever to get to carousel

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

It was out first time flying Air Canada and it was ok, comfort-wise. I hope airlines are able to get a quiet room installed for young children flying. Screaming and crying the whole time in business class is quite unfortunate. That was the only thing that really messed up the experience.

Staff were very friendly. Plane left on time and arrived on time.

The Flight Attendant was particularly helpful to my wife, who was having a bad day.

It is air Canada so leaving 20 minutes late is very acceptable

One United employee a little impatient, also on flight WiFi was out for some time. I was happy to receive a complimentary alcoholic beverage for volunteering to check my carry on bag.

Everything was great, staff, planes, at the gate. All around everything was a pleasure flying .

I COULD NOT GET ON THE FLIGHT BECAUSE THE AIR CANADA CHECK-IN STAFF COULD NOT CHECK ME IN NEITHER COULD THEY DIRECT ME TO THE ALTERNATIVE CHECK-IN AIRLINE I DIDN'T FLY AND HAD TO REBOOK ANOTHER AIRLINE, PORTER FOR THE FOLLOWING DAY. I NEED MY REFUND FOR THE RETURN LEG

When a person pays 500 $ for one way ticket that person should have better seat not the seat before the bathrooms.🤔🤨

Seating is very tight. We were delayed 90 minutes to board, because the flight crew were late
