FAQs for booking Orlando to Ontario flights

  • What information should I provide to reserve a flight for a minor?

    United Airlines asks for the names, contact details, and addresses of the adults who will bring your child to MCO Airport and meet them at Ontario International Airport (ONT). These can be legal guardians, parents, or responsible adults. Pay the Unaccompanied Minor service fee during the online reservation or at the check-in counter. Avoid paying tickets via telephone since they cost more.

  • Will I pay extra for pre-assigned seats when traveling with children?

    When children and an accompanying adult are on the same booking, Frontier guarantees adjacent seats to allow the family to sit together in their chosen class of service. You will not pay a fee for these pre-assigned seats. Avoid changing your seats once your family has been assigned adjacent seats.

  • Can I carry two pets when flying from Orlando to Ontario Airport?

    You may have two pets aboard a Delta flight, provided they are of a similar breed. If you bring two cats, they should be ten weeks to 6 months old, fit comfortably in the kennel, and be compatible. You will not be charged double since they count as one baggage.

  • Will I get stowage of my assistive devices?

    American Airlines does not count mobility and medical devices as carry-on baggage. You can put your walker, cane, footrests, and CPAP machine in the under-seat or overhead stowage spaces. If it's too bulky, it will have to be checked. If you have a battery-powered assistive device, contact the airline's Special Assistance number to confirm your battery is suitable for air travel per FAA guidelines.

KAYAK’s top tips for finding a cheap flight from Orlando Airport to Ontario

  • Southwest Airlines presents stopovers in cities like Denver (DEN), Austin (AUS), Dallas (DAL), and Chicago-Midway (MDW). American Airlines has two route options through Dallas-Fort Worth (DFW) or Phoenix Airport (PHX) as layover destinations. United Airlines connects flights in Denver (DEN) or San Francisco (SFO). Frontier Airlines and Delta Air Lines offer Atlanta (ATL) as a possible stopover, while JetBlue stops at John F. Kennedy International Airport (JFK). Alaska Airlines includes Seattle (SEA) as a layover destination, and Spirit Airlines offers a stopover in Dallas-Fort Worth (DFW).
  • Southwest Airlines provides four fare categories: Wanna Get Away (non-refundable but reusable as flight credit), Wanna Get Away Plus (non-refundable but transferable to a same-day standby flight), Anytime (refundable and reusable), and Business Select (refundable and reusable). If you must cancel your flight, do so at least 10 minutes before departure. There are no flight change or cancelation fees; fare difference applies if you rebook a higher-fare flight.
  • Before checking in online with Spirit Airlines, find out whether you are eligible. This option is available for all US citizens, but non-citizens from other countries must check in at the Orlando International Airport (MCO) ticket counter. Other exemptions include unaccompanied minors, guests with infants and pets, passengers in a group reservation (10), military personnel, and those who pre-book extra seats and space for special items.
  • Fly with the greenest airline in America – Alaska Airlines – one of the most fuel-efficient airlines with modern aircraft and flight optimization. In May 2022, it had the lowest rate of CO2 emissions per seat per mile of any full-service carrier (128 g). A high seat density is the hallmark of Alaska Airlines' 737s. With 23 of the 737 MAX 9 models in its fleet, it offers improved efficiency.
  • You don't have to sit in the regular Economy or Core seat for your flight on JetBlue with 32 inches of pitch. Instead, choose Even More Space with a 35-inch pitch in the first five front rows and 38" in the two exit rows. You'll also be entitled to early boarding, expedited security checks at MCO Airport, and overhead storage.

It was a perfect flight in all aspects! Both legs!

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

I had a wonderful flight, but the only thing that annoyed me was how crowded TSA was. I still believe airports and all planes work together to bunch everyone together to drive up cost.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Seats are much much more comfortable than United, which is what I usually fly

Everything was great. Great service, excellent communication, and early arrival

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

I liked all the informational texts. I always knew where to go and when .

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.

The boarding crew was incredibly helpful getting me on an earlier flight

Bigger seats. Board back to front! Disembark front to back!

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

This flight didn’t happen because AA agents didn’t let us board the flight

AA can't control the weather. But the airplane was hot and stuffy while stuck on the runway with a broken entertainment system.

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

The service and food needs to improve to catch up with other international flights

Would have been good to have a meal since it was a 5.5 hour flight

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

They switched my flight to Spirit, Never using Kayak again,

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

Everything went as planned. Crew was great. Seats were still not that comfortable.

They cancelled the flight and did nothing. I should be compensated for my uber rides to and from airport. Not a good service by frontier or kayak.

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.

The check in process was a mess for no reason. I spent an hour waiting in line trying to get them to print my boarding pass and as a result I missed my flight.

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.
